Statement 1: If two waves of same amplitude produce a resultant wave of same amplitude, then the phase difference between them will be Statement 2: The resultant amplitude of two waves is equal to vector sum of amplitudes treated as vectors

Answer: (A)

Solution

Resultant amplitude ; for , , so , hence Statement 1 is true; the resultant amplitude is the phasor (vector) sum , so
