A plane wave passes through a convex lens. What is the geometrical shape of the emerging wavefront ? |
planar diverging spherical converging none of these |
converging |
A convex lens is a converging lens. As the wave passes through the lens, they get converged towards the focus. So, the wavefront will be of the shape of converging spherical surfaces as the wave is refracted from the lens. |
