A wave oscillates up and down two complete cycles each second. If the wave travels an average distance of 6 m in 1 s, its wavelength is
A)0)5 m.
B)1 m.
C)2 m.
D)3 m.
E)6 m.

Question

Quizplus · Accepted Answer

The frequency of the wave is 2 Hz (since it completes two cycles per second). The speed of the wave is 6 m/s. Using the formula for wave speed, v = frequency × wavelength, we have 6 m/s = 2 Hz × wavelength. Solving for wavelength gives a wavelength of 3 m.
