Interference, Coherent and Incoherent Sources

Find the maxinum intensity in case of interference of n identical waves each of intensity I_(0) if the interference is (a) coherent and (b) incoherent.

Interference fringes are obtained due to the interference of wave from two coherent sources of light with amplitudes a_(1) and a_(2)(a_(1)=2a_(2)) . The ratio of the maximum and minimum intensities of light in the interference pattern is

n identical waves each of intensity I_(0) interfere each other. The ratio of maximum inensities if interference is (i) coherent and (ii) incoherent is

In interference pattern, using two coherent sources of light, the fringe width is …… .

As a result of interference of two coherent sources of light, energy is

The resultant amplitude in interference with two coherent sources depends upon-

The resultant amplitude in interference with two coherent source depends upon –

The resultant amplitude in interference with two coherent sources depends upon :

Statement-1: Light from two coherent sources that are not in phase does not produce an interference pattern. Statement-2: Incoherent sources do not produce a sustained interference pattern.

Intensity of central bright fringe due to interference of two identical coherent monochromatic sources is I. If one of the source is switched off, then intensity of central bright fringe becomes :
