Correct option is B
The correct answer is (b) 1/f = (1/u) + (1/v)
Explanation:-
- Object distance(u): It is the distance between the object placed and the incidence point.
- Image distance(v): 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 1/f = (1/u) + (1/v).
