What is interference and stationary interference?
(N/A) Interference is the phenomenon where two or more light waves of the same frequency and constant phase difference superpose to form a resultant wave of greater,lower,or the same amplitude.
Stationary interference (or sustained interference) occurs when the interference pattern remains constant over time. For this to happen,the two sources of light must be coherent,meaning they must emit waves of the same frequency and maintain a constant phase difference.
