Question

What is meant by power of a lens? Give its SI Units. When two or more lenses are placed in

contact, what will be their combine power​

Answer 1

Answer:

The power of a lens is defined as the ability of the lens to converge or diverge the incident ray of light on it. Its SI unit is dioptre and the combined power of two or more lenses in contact is the sum of their individual powers.

Answer 2

When two or more LENS are in contact than their combine power is =

P =p1+ p2+p3 +p4 ...................pn
