Huygen’s principle of secondary wavelets may be used to

A

Find the velocity of light in vacuum

B

Explain the particle behaviour of light

C

Find the new position of the wavefront

D

Explain photoelectric effect

Solution

(c) Huygen's principle states that every point on a wave-front may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light. The new wave-front is the tangential surface to all of these secondary wavelets.

You have learnt in the text how Huygens’ principle leads to the laws of reflection and refraction. Use the same principle to deduce directly that a point object placed in front of a plane mirror produces a virtual image whose distance from the mirror is equal to the object distance from the mirror.
