A plane wave front falls on a convex lens. The emergent wave front is

Define a wave front .

Plane wave front can be obtained form

Draw a diagram to show refraction of a plane wave front incident in a convex lens and hence draw the refracted wave front

Draw a diagram to show refraction of a plane wave front incident in a convex lens and hence draw the refracted wave front

A : The geometrical shape of the wave front when a wavefront passes through a convex lens will be again plane wave front R : Whne a plane wave front is reflected by a concave mirror, it remains as plane wavefront.

What is wave front?
