29Superposition InterferenceEasy1 mark
Waves are emitted by two coherent sources. The two waves meet at point X where they have a constant phase difference of . At point X, the amplitude of one of the waves is 0.50 m and the amplitude of the other wave is 0.30 m. The waves superpose. What is the amplitude of the resultant wave at point X?
