Question

when two waves with same frequency and constant phase difference interfere
why loss in energy,??

Here is your answer..

So, #Thé aNswer is.. : Multiple beams. Interference occurs when several waves are added together provided that the phase differences between them remainconstant over the observation time. It is sometimes desirable for severalwaves of the same frequency and amplitude to sum to zero (that is,interfere destructively, cancel).
