State the relationship between object distance, image distance, and focal length of a spherical mirror.


Open in App
Solution

Object distance: It is the distance between the object placed and the incidence point.

Image distance: It is the distance to the center line of the lens of an image.

Focal length: It is the one-half of mirror radius of curvature.

The formula of focal length: f=R/2

Hence, the relationship between object distance, image distance, and focal length of a spherical mirror is 1v+1u=1f.
