Homework Statement
i know that for intefernece of light waves to occur , the light waves must be coherent. How if two light waves are incoherent?
according to my notes, inteference can still occur if waves are not coherent, but the position of pattern will shift constantly with time to give a uniform illumination.
Homework Equations
The Attempt at a Solution
