Convex Lens

Asked by aruni_maiyer | 30th May, 2010, 06:32: PM

Expert Answer:

A lens works by the difference in refractive index between the material in the lens and the surrounding medium. So a lens put in a medium that has exactly the same refractive index as that of lens would make the lens work as a plane glass and it wouldn't bend light at all.

Hope this helps.
