Answers

Answered by navrajkalsi2005

When the refractive index of a lens is equal to the refractive index of a liquid in which it is immersed,then the lens acts as a plane glass sheet. When the refractive index are same,then the focal length of a lens becomes infinity and hence it acts as a plane glass sheet.
