The radius of curvature of a spherical mirror is 80cm. What is its focal length ? |
|
Answer» tion:Given-Radius of curvature, R = 80 cmRadius of curvature of a SPHERICAL mirror= > 2 x focal length(f)=> R = 2F=> f = R/2=> f = 80/2=> f = 40cm.Hence, the focal length of the given spherical mirror is 40cm. |
