A string fixed at both ends is driven by a tuning fork to produce standing waves.If the tension in the string is increased,
A)the frequency increases.
B)the frequency decreases and the wave velocity remains constant.
C)the wavelength decreases.
D)the wave velocity increases.
E)the wave velocity decreases.

Question

Quizplus · Accepted Answer

The wave velocity on a string is given by the formula v = sqrt(T/μ), where T is the tension and μ is the linear mass density. Increasing the tension increases the wave velocity.
