Question

Water waves with wavelengths of 1.0 m, frequencies of 1.0 Hz, and amplitudes of 20 cm traveling to the east run into waves with the same wavelength, frequency and amplitude moving to the west. The result is

Answer 1

When two identical waves moving in opposite directions meet each other then a standing wave is created whose features are:

1)maximum amplitude is twice the individual amplitude

2)gap between point of 0 displacement (nodes) is half of wavelength.

Hence the maximum amplitude at antinode is 40 cm.and distance between adjacent nodes is 0.5 m
