Question

what is formula of mirror

Answer 1

Hey there!!!

Formula of mirror is -

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$
where , f = focal length

v = Distance of image from pole


u = Distance of object from pole

Hope this helps u !!!

Answer 2

The mirror equation is
1/f= 1/v+1/u.
Where f is focal length, v is image distance and u is object distance.
Magnification (M) = - v/u.

Hope my answer helps you.
