Question

some formulas for refraction at spherical surface and lenses​

Answer 1

Hey dear ‼️

Lens formula...

The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula (lens equation), given by:

1/v-1/u=1/f...

This is applicable to both types of lenses.

Answer 2

Answer:

Hey mate.....

Here's ur answer :

The relationship between distance of object(u), distance of image (v) and the focal length (f) is known as Len's Formula.

and it is given as :

»» 1/f = 1/u + 1/v

»» This formula is applicable for both types of lenses (concave and convex lens)
