Answer 2

hi friends,

Under what condition a

convex lens when placed in a medium behaves as an ordinary glass plate?

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 would not be a lens, it would not bend light at all.

Hope this helps.
