Derive concave lens formulae

Answer 1

hey mate!

Derivation of Lens Formula for concave lens: Let AB represent an object placed at right angles to the principal axis at a distance greater than the focal length f of the convex lens. The image A1B1 is formed between O and F1 on the same side as the object is kept and the image is erect and virtual.

Answer 2

Heya Friend,

For Every Both Lenses, concave and convex lens, lens formulae is 1/v - 1/u = 1/f....

{I have illustrated the formula in the attachment with the help of convex lens....}.

Hope that helps...
