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 ?

When a wave travels from a denser to rarer medium, then

A : When a light wave travels from a rarer to a denser medium, it looses speed. The reduction in speed imply a reduction in energy carried by the light wave. R : The energy of a wave of proportional to frequency of wave.

Assertion: When a light wave travels from a rarer to a denser medium, it loses speed. The reduction in speed imply a reduction in energy carried by the light wave. Reason: The energy of a wave is proportional to velocity of wave.

Fill in the blanks to complete the following sentence: Q: When light travels from a rarer to a denser medium, its speed _____

A: When light travels from a rarer to a denser medium, it loses some speed but it doesn't imply a reduction in the energy carried by the light wave. R: Energy carried by a wave depends on the amplitude of the wave and not on the speed of wave propagation.
