Question

If a, b and r denote the object distance, image distance and radius of curvature respectively of a spherical mirror, then find out the relation between them.

Answer 1

The relation between object distance, image distance and focal length of a spherical mirror is:

I/f=1/u+1/v



where f = focal length of spherical mirror

            u = object distance, and

            v = image distance

Answer 2

Distance between pole and object is called....object distance...

Distance between pole and image is called........ image distance....

Distance between pole and the principal focus of the mirror.........is called.....focal length

Hope it helps.....
