When a plane wavefront of light is incident on the separating surface between two media, the reflected wavefront is of same width like the incident wavefront whereas the refracted wavefront is of different width. Explain?

A plane wavefront AB is incident on a concave mirror as shown. Then,the reflected wavefront will be

A plane wavefront incident on a reflecting surface at an angle of 30^(@) with horizontal. Find the angle of reflected wavefront with horizontal

Assertion :- When monochromatic light is incident on a surface separating two medium, the reflected and refracted light has same frequency as incident light. Reason :- Reflection and refraction arise through interaction of incident light with atoms of matter and atoms act as oscillator which takes up frequency of incident light and undergoes forced oscillation and scatters light of same frequency.

Explain the following giving reasons : (i) When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency. (ii) When ligjt travels from a rarer to a denser medium, the speed decreases. Does this decrease in speed imply a reduction in the energy carried by the wave ? (iii) In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. What determines the intensity in the photon picture of light ?
