A 50.0cm long oscillating string establishes the standing wave shown below. The five waves shown are snapshots of the string taken at 0.012s intervals. The displacements observed at 1 and 5 are the maximum displacements of the string. a) Find the period, frequency, and wavelength for the travelling waves on this string.

b) In what harmonic is the string vibrating?

c) What is the speed of the travelling waves on the string?
