Answer 1

here is derivativtion hope you understand

Answer 2

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 for both, plane mirrors and spherical mirrors (convex and concave mirrors). The mirror formula is written as:

1/f = 1/v + 1/u
