1.Explain what is meant by Huygen’s principle.

Use the principle to show that a plane wave incident obliquely on a plane mirror is reflected:

• As a plane wave,
• So that the angle of incidence is equal to the angle of reflection

2.*A beam of light is refracted at the boundary of two media. Using Huygen’s principle show how the ratio of the sine of the angle of incidence to the sine of the angle of refraction is related to the speeds of light in the two media.

1.Using Huygen’s principle in secondary wavelets explain, making use of a diagram, how a refracted wavefront is formed when a beam of light, traveling in glass, crosses the glass-air boundary. Show how the sines of the angles of incidence and refraction are related to the speeds of light in air and in glass.
