In the figure, which of the curves best represents the variation of wave speed as a function of tension for transverse waves on a stretched string?

Question

Quizplus · Accepted Answer

The speed of a wave on a stretched string is dependent on the tension and the linear mass density of the string. As tension increases, the speed of the wave will also increase according to the equation v = √(T/μ), where T is the tension and μ is the linear mass density. Curve B shows an increasing trend in wave speed with increasing tension, which is consistent with this equation, making it the best choice.
