Question

A string with a mass density ? = 4.50×10^-3kg/m is under a tension of F = 224 N and is fixed at both ends. One of its resonance frequencies is 178.0 Hz. The next higher resonance frequency is 222.5 Hz. a)What is the fundamental frequency of this string?

D)Now, suppose the same string is detached at one end and connected by a ring to a frictionless post, so that it can move freely. Find the wavelength of the first (fundamental) harmonic.

E) What is the frequency of the third (n = 3) harmonic in this case?

HELP ME WITH D and E!!!!
