A sound wave with a frequency of 11 kHz propagates in a steel rod at a speed of 5.5 km / s. What is the wavelength?

The wavelength is determined from the equation
l = v / f,
where v = 5.5km / s = 5500m / s is the speed of sound in the rod, and
f = 11kHz = 11000Hz – sound wave frequency.
l = 5500/11000 = 0.5m = 50cm
