Define the following term in the context of spherical mirrors:- Centre of curvature
Which type of mirror can form a real image?
What kind of mirror is required for obtaining a virtual image of the same size as the object?
What is meant by magnification? Write its expression. What is its sign for the (a) real (b) virtual, image?
The focal length of a concave mirror is 10 cm. Find its radius of curvature.
AB is the object, A1B1 is its image. MM' is the position of the mirror. Complete the ray diagram and find the position of the center of curvature and focus of the mirror. Also, measure the focal length.
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.
