Question

For a spherical mirror ______ *


f = R/2

f = 2R

f = R

f = R/4

​

Answer 1

Answer:

For a spherical Mirror

Focus Should be Half of Radius of Curvature

F = R/2

Thankyou.

Answer 2

Answer:

f=r/2

Explanation:

For a spherical mirror having small aperture, the principal focus (f) lies exactly between the pole (P) and centre of curvature (C). So the focal length of a spherical mirror is equal to half of its radius of curvature. If f is the focal length of a spherical mirror and R is its radius of curvature, then:

                                         f = R/2
