Exercise A string has a mass per unit length of 2.50 g. m-1 and is put under
a tension of 25.0 N as it is stretched taut along the x-axis. The free end is attached to a tuning fork that vibrates at 50.0 Hz,
setting up a transverse wave on the string having an amplitude
of 5.00 mm. Determine the speed, angular frequency, period,
and wavelength of the disturbance.​
