Two waves of equal amplitude A, and equal frequency travel in the same direction in a medium. The amplitude of the resultant wave is

Two waves of equal frequency f and velocity v travel in opposite directions along the same path. The waves have amplitudes A and 3 A . Then:

During superposition of two waves of nearly equal frequencies , beat frequency is defined as the

Two waves of equal amplitude 1m and equal frequency travel in the opposite direction in a medium. The magnitude of amplitude of the resultant wave may not be

A standing wave arises on a string when two waves of equal amplitude , frequency and wavelength travelling in opposite superimose. If the frequency of oscillation of the standing waves

Two interferring waves have the same wavelength, frequency and amplitude. They are travelling in the same direction but 90^(@) out of phase compared to individual waves. The resultant wave will have the same.
