What kind of mirror is required for obtaining a virtual image of the same size as the object?
Name the spherical mirror which can produce a virtual and diminished image of an object.
What is a spherical mirror?
Draw a ray diagram to show the formation of image by a concave mirror for the object beyond its centre of curvature. State three characteristics of the image.
What is meant by magnification? Write its expression. What is its sign for the (a) real (b) virtual, image?
Define the following term:
convex mirror
What is the relation between focal length and radius of curvature of a concave mirror?
The following Figure shows a concave mirror MM' on which a ray of light incident from a point P gets reflected to meet the principle axis at O.
(a) Find, by construction, the position of the centre of curvature of the concave mirror.
(b) Write down the value for the radius of curvature of the mirror.
(c) Calculate the focal length of the mirror.
(d ) Which relation is used in deducing the focal length from the radius of curvature?
The diagram below shows the parallel rays incident on a convex mirror. C is the centre of the curvature of the mirror. By drawing the paths of the reflected rays, label the focus F and hence find the focal length of the mirror.
