A steel wire of mass 4 0 g and length 80 cm is fixed at the two ends. The tension in the wire is 50 N. Find the frequency and wavelength of the fourth harmonic of the fundamental.

Question

Philoid · Accepted Answer

Fundamental frequency,

So, frequency of 4^th harmonic is, F₄=4ᳵ62.5=250 Hz

Now,

F₄₄=

₄40 cm
