A string is strung horizontally with a fixed tension.A wave of frequency 100 Hz is sent along the string,and it has a wave speed of 50.0 m/s.Then a second wave,one of frequency 200 Hz,is sent along the string.What is the wave speed of the second wave?
A)25.0 m/s
B)50.0 m/s
C)70.7 m/s
D)100 m/s

Question

The wave speed is determined by the tension and the linear mass density of the string, which are both constants in this scenario. Therefore, the wave speed of the second wave is also 50.0 m/s. The frequency of the wave does not affect the wave speed.

A String Is Strung Horizontally with a Fixed Tension
