AB is the semi circular object of diameter (f/2) where f is the focal length, placed on the principal axis of a concave mirror with point A at the centre of curvature. A'B' is the image formed . The correct option is (Assume diameter of the object is along principal axis)

Define the following terms related to curved mirrors : (A) Focus (b) Principal axis ( c ) Centre of curvature (d) Radius of curvature

Define: Radius of curvature and centre of curvature

Two identical concave mirrors M_(1) & M_(2) with principal axes perpendicular to each other and pole P_(1) of mirro M_(1) at origin is as shown. Let f be the focal length and C be the common centre of curvature for both mirrors. A point object O is at (-5f,0) and is moving with a velocity vecC=v_(0)hati m/s. Consider rays incident on mirror M_(2) the co-ordinates of the final imasge formed is

Define the terms pole, principal axis and centre of curvature with reference to a spherical mirror.

The values of d_(1) & d_(2) for final rays to be parallel to the principal axis are: (focal lengths of the lenses are written above the respective lenses in the given figure)

STATEMENT-1: A lens has two principal focal lengths which may be different in magnitude. STATEMENT-2: The distance of both principal focus from optical centre of lens depend on the two radii of curvature of the lens. Distance of both principal focus from optical centre a lens are same only if radii of curvature of both sides of lens are same
