## Homework Statement

The equation of a travelling transverse wave is

y=2.0sin 2π(x/30 - t/0.01)

where x and y are in centimetres and t is in seconds.

When attached at both ends, a string under a tension of 480 N and having a linear density of 1.20 x 10-2 kg/m resonates at a frequency of 150 Hz. The next highest frequency at which the string resonates is 200 Hz.

(i) What is the fundamental frequency of vibration for this string under this tension?

(ii) What is the string’s length?
