Is it necessary to have two waves of equal intensity to study interfrence pattern? Will there be an effect on clarity if the waves have unequal intensity?

Ground wave have wavelength

Is it always true that for two sources of equal intensity, the number of photons emitted in a given time are equal?

Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

a. 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. Explain why. b. When light travels from a rarer to a denser medium, the speed decreases. Does the reduction in speed imply a reduction in energy carried by the light wave? c. In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. What determine the intensity of light in the photon picture of light?

In an interference pattern, the ratio of maximum intensity to minimum intensity is 25:1. Find the ratio of the amplitudes and intensities of the two interfering waves.

Two light sources have intensity of light as I_(0) , What is the intensity at a point where the two light waves have a phase difference of pi//3 ?

Suggest a possible explanation. As you have learnt in the text, the principle of linear super position of wave displacement is basic to understanding intensity distributions in diffraction and interference patterns. What is the justidication of this principle?
