David Sang and Graham Jones Solutions for Chapter: Waves, Exercise 6: Questions

Sound is a mechanical wave that can be transmitted through a solid. Calculate the frequency of sound of wavelength $0.25 \mathrm{m}$ that travels through steel at a speed of $5060{ \mathrm{ms}}^{-1}$

A cello string vibrates with a frequency of $64 \mathrm{Hz}$. Calculate the speed of the transverse waves on the cello string given that the wavelength is $140 \mathrm{cm}$.

An oscillator is used to send a transverse wave along a stretched string. The wavelength of the wave is $5.0 \mathrm{cm}$ when the frequency of the oscillator is $30 \mathrm{Hz}$. For this wave, calculate:

(a) Its frequency
