Tripling both the tension in a guitar string and its mass per unit length will result in changing the wave speed in the string by what factor?
A)0.58
B)1.00 (i.e. ,no change)
C)1.73
D)3.00

Question

The wave speed on a string is given by the formula v = sqrt(T/μ), where T is the tension and μ is the mass per unit length. Tripling both T and μ results in v = sqrt(3T/3μ) = sqrt(T/μ), so the wave speed remains unchanged.
