Two waves executing simple harmonic motion travelling in the same direction with the same amplitude and frequency are superimposed. The resultant amplitude is equal to $\sqrt3$ times the amplitude of individual motions. The phase difference between the two motions is ______ (degree).
Numerical value type. Enter your answer.
Answer: 60
$$A_R^2 = 2A^2(1 + \cos\phi) = 3A^2\ \Rightarrow\ \cos\phi = \frac12\ \Rightarrow\ \phi = 60^\circ$$
