22PRACTICE PROBLEM
Solids can transmit both longitudinal and transverse waves. Thus, sound waves can exist as transverse and longitudinal waves in a solid. An example is the propagation of earthquakes through the Earth's crust. Suppose longitudinal waves travel at a speed vl and transverse waves travel at a speed vt; where vl > vt. The two waves arrive at a recorder located at a point P, separated by a time Δt. Derive an expression for the length, L, measured from the point a wave is generated to the point P. Take the waves to travel in a straight line even though the waves follow complex routes due to the non-uniform nature of the medium.
