To produce beats it is necessary to use two waves:
A)traveling in opposite directions
B)of slightly different frequencies
C)of equal wavelengths
D)of equal amplitudes
E)whose ratio of frequencies is an integer

Question

Quizplus · Accepted Answer

To produce beats, two waves of slightly different frequencies are needed. The difference in frequency between the waves determines the rate at which the amplitude of the resultant wave oscillates, creating the beat. Waves traveling in opposite directions (A) can result in interference patterns but not necessarily beats. Equal wavelengths (C) and equal amplitudes (D) do not play a role in producing beats. The ratio of frequencies being an integer (E) can result in resonance but not necessarily beats.
