Ofcourse convex lens is a converging lens but in a special case when *(the refractive index of the surrounding medium is greater than the refractive index of lens material) then is acts as diverging lens. Likewise in concave lens for the same condition*() mentioned above it acts as converging lens.

hey, u 're wrong.... convex lens is converging, not diverging!!

Nivetha Vijayakumar 6 years, 9 months ago

The reason is that, the refractive index of the medium is greater than the refractive index of the lens. Hence, it acts as diverging lens.
