Two waves traveling on a string in the same direction both have a frequency of 141 Hz, a wavelength of .43 m, and an amplitude of .16 m. What is the amplitude of the resultant wave if the original waves differ in phase by n/4 rads?
What is the phase difference between the two waves if the amplitude of the resultant wave is .12 m?
