The focal length of spherical mirror is

If the focal length of a spherical mirror is 12 cm , what is the value of its radius of curvature?

If we say that the focal length of a spherical mirror is n times its radius of curvature, then n must be

If the focal length of a spherical mirror is 12.5 less cm, its radius of curvature will be :

If the focal length of a spherical mirror is 10 cm , what is the value of its radius of curvature?

The focal length of a spherical mirror is given by f=R/2 , where R is radius of curvature of the mirror. For a given spherical mirror made of steel the focal length is f = 24.0 cm. Find its new focal length if temperature increases by 50^(@)C . Given = alpha_("Steel")=1.2 xx 10^(- 5).^(@)C^(-1)
