CBSE Class 10 Answered

Is it possible for a lens to act as a convergent in one medium and divergent in other
Asked by sourabhprakash | 28 Feb, 2010, 12:11: AM
answered-by-expert Expert Answer

Dear student,

Yes. In a lens  light travels from a less dense medium (air) into a more dense medium (glass) it bends toward the surface normal. And when it travels from a more dense medium to a less dense medium it is bent away from the surface normal.

So if the lens were placed in a more dense medium then itself the typical direction of light bending would be reversed. 

Hope this helps.
