Give one use each of a concave and a convex mirror. Hence, it is also called a diverging mirror. The image produced by a convex mirror is called a virtual image. Answer: Convex Lens Concave Lens. (b) concave mirror (c) convex mirror (d) plane mirror. A convex mirror is the kind of mirror used for security in stores, and is also the kind of mirror used on the passenger side of many cars ("Objects in mirror are closer than they appear."). Unlike concave mirrors, convex mirrors always produce images that have these characteristics: (1) located behind the convex mirror (2) a virtual image (3) an upright image (4) reduced in size (i.e., smaller than the object) The location of the object does not affect the characteristics of the image. Image formed is virtual Image formed is real. A convex mirror is … Then we will get a sharp image. 3.1 Images formed by Mirrors and Lenses • Images • Image formation by mirrors • Images formed by lenses Object-Image • A physical object is usually observed by reflected light that diverges from the object. Here the image formed in front of the mirror. Assertion (A): For observing traffic at back, the driver mirror is convex mirror. (A summary of the three cases or types of image formation appears at the end of this section.) Convex mirror always give smaller image. In this section, let us look at the types of images formed by a convex mirror. (C) An image formed by a _____ mirror is always of the same size as that of the object. The table below represents the image formation of a convex mirror when an object is placed at a different position. But if the object is placed between the focus and pole, the image formed is virtual and erect. The size of the image formed by the convex mirror is always smaller than that of the object. In this section, let us look at the types of images formed by a convex mirror. Lenses: A convex lens with only one lens to magnify the object. Location of the image is always between the focal point and vertex of the mirror. (a) 1. As such, the characteristics of the images formed by convex mirrors are easily … When an object is placed at infinity, a virtual image is formed at the focus. Explanation: A virtual image is always created by a convex mirror, and it is always situated behind the mirror. 1) A concave mirror always forms an enlarged real image of a real object. The size of the image is much smaller than compared to that of the object. Rays of light parallel to the principal axis after reflection from a concave mirror meet at a point (converge) on the principal axis.

A convex mirror is a type of spherical mirror in which the reflecting surface is the bulged out portion of the sphere. The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. Case 3: If the object is placed beyond C. Virtual images are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F. Plane mirrors and convex mirrors will always produce an upright image. The image formed by the convex lens may be equal in size, smaller or larger than the object while concave lens always forms diminished/smaller image of the object. 4) The image is real if the distance of the object from the lens is greater than the focal length and virtual if it is less than the focal length. 4. will always be magnified. 9. As the object approaches the mirror the image also approaches the mirror and grows until its height equals that of the object. A virtual image is always erect. Convex mirror is used in rear view mirror. 4. will always be magnified. i) Concave mirror:-is a spherical mirror whose reflecting surface is curved inwards. The image is formed at infinity. This implies, the image distance is always positive in case of convex mirror and the image is always formed on the other side of the object i.e., behind the convex mirror. Then we will get a sharp image. IN CASE OF CONVEX MIRROR: A convex mirror always forms a virtual and erect image. Q8. A different type of image is formed when an object, such as a person’s face, is held close to a convex lens. Page Number: 171. 1. When an object lies between F and P: when an object lies between principal focus and pole of the mirror, the image formed is magnified, virtual, and erect. 2.

Convex mirrors reflect light outwards, therefore they are not used to focus light. A concave mirror is used as doctor's head mirror to focus light on body parts like eyes, ears, nose etc., to be examined because it can form erect and magnified image of the object. (E) An image formed by a concave _____ cannot be obtained on a screen. As inferred from the ray diagrams, the image formed by a convex mirror is always virtual, erect, and smaller. A convex mirror enables the driver to view such larger area of the traffic behind him. Answer. (A summary of the three cases or types of image formation appears at the end of this section.) This image, formed by light rays leaving the flat refractive surface, is Select one: a. real and closer to the viewer than the object. 10. A virtual image has the following properties: 1. The image is formed at infinity. A convex lens of small focal length and its primary use is to see the magnified image of small objects. 3) A convex mirror never forms a real image of a real object. If we placed an object above the x-axis then by geometry the rays will converge below the axis. SHOW ANSWER. Therefore, the image formed will be an inverted image. A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. A convex lens of small focal length and its primary use is to see the magnified image of small objects. Related Lesson: Summarizing Image Formation by Mirrors | Geometric Optics. Can you explain this answer? 1. always be real. In a convex mirror, the virtual image formed is always diminished, whereas in a concave mirror when the object is placed between the focus and the pole, an enlarged virtual image is formed. The image produced by a convex mirror is called a virtual image. The image formed from any real object is always smaller than the object. The image through the concave lens is always a virtual image, standing like an object, and looks smaller than the real thing. An incident ray which is parallel to the principal axis is reflected as if it came … Question 2. Two convex lenses: Focal length Question 2. A convex mirror enables the driver to view such larger area of the traffic behind him. When the object is far away from the mirror the image is upright and located at the focal point. According to the graphical method, the image produced by a convex mirror can always be located by drawing a ray diagram according to four simple rules: . A different type of image is formed when an object, such as a person’s face, is held close to a convex lens. Images formed with convex mirrors are always right side up and reduced in size. Convex mirrors reflect light outwards, therefore they are not used to focus light. Reason (R): In concave spherical mirror the image formed is always virtual.

A convex mirror enables the driver to view such larger area of the traffic behind him. A convex mirror always forms a virtual, erect and diminished image. But a virtual image of an object is always formed in a convex mirror. A concave mirror will only produce an upright image if the object is located in front of the focal point. They are concave mirror and convex mirror. A real image can be captured on a screen and is formed by a concave mirror and convex lens. A plane mirror always produces the images that have a magnification of '1.' The size of the image is much smaller than compared to that of the object. If the object is placed at 25 cm in front of the concave mirror having focal length 20 cm, this means that the object is placed in between focus and the centre of curvature of the mirror. The image formed by a mirror is always straight whatever will be the distance, then mirror is: (a) Only plane (b) Only concave (c) Only Convex (d) Either plane or convex. A convex mirror is the kind of mirror used for security in stores, and is also the kind of mirror used on the passenger side of many cars ("Objects in mirror are closer than they appear."). c. may be either real or virtual. A convex mirror forms a virtual, diminished and upright image of an object. When the reflection of an object is seen in a flat mirror? The two possibilities are- when the object is at infinity and the object is between pole and infinity. Types Of Images. There is a definite relationship between the image characteristics and the location where an object is placed in front of a concave mirror. When the reflection of an object is seen in a convex mirror the image will? Convex mirror: It is that in which the reflection occurs through outer surface of mirror. The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.A virtual image is a copy of an object formed at the location from which the light rays appear to come. 1) The matter absorbs or reflects the light. A convex mirror always produces an erect image of the objects. Hence, magnification produced by rear view mirror is always less than 1. When the object is far away from the mirror the image is upright and located at the focal point. Using mirror formula, 1v+1u =1f ⇒ 1v = 1f-1u Object distance u is negative and the focal length f is positivefor convex mirror. Transcribed image text: 12. (i) It always forms a virtual, erect, and diminished image. Concave mirror, 2. The rear view mirror of a car is a plane mirror. [Note : The exercise helps you deduce algebraically properties of … 7. Virtual image and real image of convex lens The convex lens differs greatly depending on whether the object is inside the focus of the concave mirror. A virtual image is produced when the light rays from a source don’t cross or meet at a point to form an image. object, then the mirror is (a) concave (b) convex When they appear to meet at a point(the rays of light), it forms a virtual image and a virtual image is ALWAYS erect. Properties of an image formed by a convex mirror: The image is always formed behind the mirror, between the pole and its focus. This image, formed by light rays leaving the flat refractive surface, is Select one: a. real and closer to the viewer than the object. A plane mirror always produces the images that have a magnification of '1.' If the object is placed at 25 cm in front of the concave mirror having focal length 20 cm, this means that the object is placed in between focus and the centre of curvature of the mirror. Ques.
