Question

DOES FOCAL LENGTH OF A SPHERICAL MIRROR CHANGES WHEN IT IS COMPLETELY IMMERSED IN THE WATER pREDICT and write reason

Answer 1

Hey!! Here is your answer!!

Mirrors, spherical or otherwise, operate on the principle that the angle of reflection of a ray of light equals the angle at which it strikes the mirror's surface. That behavior is not affected by the medium in which the light travels, so the mirror's focal length would be no different in air or water.

Answer 2

Yes as radius changes
