What phase difference between two identical waves

Reference no: EM1390592

Q. What phase difference between two otherwise identical travelling waves, moving in the similar direction along a stretched string, would result in combined wave having amplitude 1.6 times that of the common amplitude of the two combining waves? Express your reply in (a) degrees, (b) radians, and (c) as a fraction of the wavelength.
