Question

What is the conditions for obtaining good interference pattern. At a point on the two slit interference pattern obtained using a source of given wavelength 5300 A0 the path difference is 4.125 m is the point at the centre bright or dark fringe? Hence, find the order of the fringe? Hellwos​

Answer 1

Answer:

The two sources of light should be coherent:

The light should be monochromatic:

The two light sources should be of equal brightness, i.e., the waves must have the same amplitude.

The two light sources should be narrow:

The interfering light waves should be in the same state of polarization:
