Text Solution

Verified by Experts

Conditions for a steady and distinct (sharp) interference pattern :
(1) The two light sources must be coherent.
(2) The two light sources should be monochromatic
(3) The two light sources should be of equal brightness.
(4) The two light sources should be narrow.
(5) The interfering light waves should be in the same state of polarisation.
(6) The two light sources should be closely spaced and the distance between the screen and the sources should be large.
