Explain the following giving reasons :
(i) When monochromatic light is incident and surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency.
(ii) When light travels from a rarer medium 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 curve. What determines the intensity in the photon picture of light ?
