Let us consider two rays, one striking the mirror at its pole and the other passing through the centre of curvature.Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.Question: When a person stands 40 cm in front of a cosmetic mirror(concave), the erect image is twice the s.

The image formed by the concave mirror may be enlarged or diminished, according to the position of the object.
And to some degree, a virtual image is more intuitive because we have so much experience with it when we think about mirrors or reflective surfaces.
Image Formation By Concave Mirrors - tutorialspointIn the majority of the cases, a concave mirror produces real and inverted images except when the object is placed very near to the mirror i.e. pole (p) and the focus (f) where the image produced is virtual and erect.Concave mirrors are often used as shaving mirrors to produce an erect, enlarged image.As the image formed by concave lens is real it can be obtained on a screen.KEY 1 Mirrors 1.) An object 5.0 cm tall is placed 7.0 cm in front of a concave mirror.The collecting mirror in turn reflects and focuses the light in an elongated focus on the second axis past an oval aperture.
Convex Mirrors are also called as Divergent Mirrors, because convex mirrors cause the rays of light parallel to its axis to diverge.An erect object is located between a concave mirror and its focal point.
Convex and concave mirrors - wonderwhizkidsBecause the image is formed by a direct projection through the mirror, it is reversed (e.g. your right eye appears as the left eye in your image, etc.).If object is at focal point F, the image is virtual and at infinity.Concave mirror is used by dentists to see larger image of teeth of the patient.
The image produced by a convex mirror of an erect objectImage Formation by Concave Mirrors There are two alternative methods of locating the image formed by a concave mirror.A virtual image is formed if the object is located less than one focal length from the concave mirror.
If the object is at a point farther from the mirror than the center of curvature, the image is real (i.e., it is formed directly by the reflected rays), inverted.The image is located behind the mirror so you cannot touch it (that is why it is called virtual).
Worksheet - Opt - Mirrors - AnswersThus, a proper combination of a convex lens with a concave mirror arranged with suitably proportioned focal lengths, permits clear, large, and upright images to be projected.But it can form a real image, if the object is virtual, i.e., if the light rays converging at a point behind a plane mirror (or a convex mirror) are reflected to a point on a screen placed in front of the mirror, then a real image will be formed. eg Throw a torch at the plane mirror.
Which way and by how much should the object be moved to double the size of the image.
