Difference among two otherwise identical travelling waves

Reference no: EM13658097

What phase difference among two otherwise identical travelling waves, moving in the similar direction along a stretched string, will result in the combined wave having amplitude 1.4 times that of the ordinary amplitude of the two combining waves? Express your answer in (a) degrees, (b) radians, and (c) as a fraction of the wavelength.
