Show the relationship between wave speed and wave frequency. If the speed of a longitudinal wave is 340 m/s and the frequency is 1000 Hz, what is the wavelength of the wave?
What will be an ideal response?
Answer: Speed = wave frequency × wavelength. So wavelength = speed/frequency =
(340 m/s)/(1000 Hz) = 0.34 m.
