How to derive mirror formula​

Answer 1

Explanation:

The derivation of mirror formula is one of the most common questions asked in various board examination as well as competitive examinations. A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’. The mirror formula is applicable both in plane mirrors and spherical mirrors (convex and concave mirrors). The mirror formula derivation is provided here so that students can understand the concept of the topic in a better way. The mirror formula is written as:

1/f = 1/v + 1/u
