State laws of reflection of light.

State the two laws of reflection of light.

Huygen.s principle of secondary wavelets can be used to a) deduce the laws of rectraction of light b) deduce the laws of refraction of light c) explain the transverse nature of light waves d) predict the location of a wavefront as time passes

Write the three characteristic features in photoelectric effect which cannot be explained on the basis of wave theory of light, but can be explained by using Einstein's equation.

State the Snell's laws of refraction of light.

Point out two distinct features observed experimentally in photolelectric effect which cannot be explained on the basis of wave theory of light. State how the 'photon picture' of light provides an explanation of these features.

Derive the law of reflection using Huygen.s Wave Theory.

State any one postulate of Huygen.s wave theory.

Which of the following properties of light conclusively support wave theory of light?

Huygens wave theory allows us to know
