A tuning fork of frequency 440 Hz is attached to a long string of linear mass density 0 01 kg m − 1 kept under a tension of 49 N. The fork produces transverse waves of amplitude 0 50 mm on the string. (A) Find the wave speed and the wavelength of the waves. (B) Find the maximum speed and acceleration of a particle of the string. (C) At what average rate is the tuning fork transmitting energy to the string?

We can get velocity of wave by, putting values in,

, putting n=440 we get,

(A)

The equation may be defined as,

So, V_max=A=0.0005 2π440=1.4 m/s

We know that,

Putting known values in the formula, we get, P=0.67W
