Question

Give the relation of mirror formula

Answer 1

Answer:

$\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$

This equation is called the mirror formula

Please mark me as the brainliest

Answer 2

Answer:

It is an equation relating object distance and image distance with focal length is known as a mirror equation. It is also known as a mirror formula.

1/v + 1/u = 1/f

Explanation:

u is the Object distance

v is the Image distance

f is the Focal Length given by f=R2

R is the radius of curvature of the spherical mirror

to put the sign values, you need sign convention for mirror. I have provided you an image for self help. Practice a bit and then you'll be perfect at this.
