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 the refraction of a plane wavefront incident on a convex lens and hence draw the refacted wavefront.

When a plane wavefront is incident on a double convex lens, the refracted wavefront is

When a plane wavefront is incident on a double convex lens, the refracted wavefront is

A plane wavefront is incident on a prism.Draw the shjape of the refracted wavefront.

(a) State Huygen's principle . Using this principle draw a diagram to show how a plane wave front incident at the interface of the media gets refracted when it propagates from a rarer to a denser medium. Hence verify Snell's law of refraction. (b) When monochromatic light travels from a rarer to a denser medium, explain the following, giving reasons- (i) Is the frequency of reflected and refracted light same as the frequency of incident light? (ii) Does the decrease in speed imply a reduction in the energy carried by light wave?

Draw a diagram to show the reflection of a light ray incident normally on a plane mirror.
