An underwater sensor produces a sound wave that travels from seawater into a steel wall.
| Medium | Speed of sound in m/s\mathrm{m/s}m/s |
|---|---|
| seawater | 1500 |
| steel | 5100 |
The wavelength of the sound wave in seawater is 0.050 m.
Calculate the wavelength of the sound wave in the steel. Show your working.
State whether the sound wave is infrasound, audible sound or ultrasound.
