Two waves of the same frequency and same amplitude are superimposed to produce a resultant disturbance wave of the same amplitude. What is the phase difference between the two original waves?
Why this question? Bottom lines: Always remember that if two wave of same frequency and different amplitude is superpose then the resultant amplitude after superposition of wave is AR=√A12+A22+2A1A2cosϕ where ϕ is phase difference between wave. |
