Question

The speed of a wave along a stretched string depends only on the tension and the linear mass density of the string and does not dependent on the frequency of the wave.

1. Give the equation of speed of transverse wave along a stretched string.

2. Why the speed does not depend on the frequency of the wave.

3. A steel wire 0.72 long has a mass of 5 × 10^-3Kg. If the wire is under a tension 60N, what is the speed of transverse wave on the wire?

Answer 1

1. v = \(\sqrt{\frac{T}{m}}\) Where T is the tension and m is the mass per unit length.

2. The frequency of the wave is determined by the source that generates the wave.

3.
