Question

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

Answer 1

Answer:

Draw a diagram to show refraction of a plane wavefront incident on a convex lens and hence draw the refracted wavefront. Refracted spherical wavefront emerges out which is converging towards the focus of a lens. You have learnt in the text how Huygens' principle leads to the laws of reflection and refraction.
