An earthquake tremor produces a longitudinal seismic wave (P-wave) that travels through the Earth's crust.
Explain what is meant by the term longitudinal wave.
The frequency of this seismic wave is 50 Hz50\text{ Hz}50 Hz.
State a typical value for the speed of a longitudinal wave in a solid.
Using your value from (b)(i), calculate the wavelength of the seismic wave in the crust.
