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

Expert Answer:

Dear student,

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.
