Question

write relation between focal length and radius of curvature?​

Answer 1

Answer:

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2. ... We know that rays of light parallel to the principal axis passing through the focus (F) of a concave mirror, after reflection.

Answer 2

• Write the relation between focal length and radius of curvature of a spherical mirror. The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.
