Question

what is mirror formula and sen formula
​

Answer 1

Answer:

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).

Explanation:

u= Object distance v= Image distance f= Focal length.

mirror formula (1/f = 1/v+1/u)

Answer 2

$Mirror \: formula \: = \frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

$Lens \: formula = \frac{1}{v} - \frac{1}{u} = \frac{1}{f}$
