Problem

A sound wave travelling through steel has a wavelength of

1.1\,\text{m}

and its time period is

2.0 \times 10^{-4}\,\text{s}

. a. (a) Calculate the frequency of the wave. b. (b) Find the speed of sound in steel. c. (c) If the same wave enters air where the speed of sound is

340\,\text{m/s}

, determine its wavelength in air.
