Use Huygen's principle to show how a plane wavefront propagates from a denser to rarer medium. Hence verift snell's law of refreaction.

Use Huygen's principle to show how a plane wavefront propagates from a denser to rarer medium. Hence verift snell's law of refreaction.

When a wave travels from a denser to rarer medium, then

When a wave travels from a denser to rarer medium, then

Verify Snell's law of refraction when a plane wavefront is propagating from denser to a rarer medium.

(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?

Using Huygen.s principle, verify Snell.s law of refraction of plane wave propagating from denser medium to rarer medium.
