Question

Two waves are said to be coherent, if they have: (A) same frequency, different amplitude, same phase (B) same frequency, amplitude and phase (C) same frequency, amplitude but different phase (D) all different

Two sources, are said to be coherent, if they vibrate in the same phase or there have constant phase difference and they must emit continuously waves of same wave length and frequency with different amplitudes.

same frequency, different amplitude, same phase

same frequency, amplitude and phase

same frequency, amplitude but different phase

all different
