Question

Assuming the waves travel in straight lines, how far away is the center of the earthquake?

The average speeds of transverse and longitudinal waves in rock are 8.9 km/s and 5.1 km/s respectively. A seismograph records the arrival of the transverse waves 73 s before that of the longitudinal waves.

Waves becoming straight is a limit problem of amplitude tending to 0 and/or the velocity of propagation ( $\frac{2 π}{p e r i o d}$ $(2pi)/(period)$ ) becoming 0, in the limit.

Explanation:

Waves become straight when amplitude tends to 0 and/or the

velocity of propagation ( $\frac{2 π}{p e r i o d}$ $(2pi)/(period)$ ) becoming 0, in the limit.

When the velocity of propagation $\to$ $to$ 0, the period $\to \infty$ $to oo$ and the

frequency $\to$ $to$ 0.

So, in my opinion, the results for this virtual limit problem are results

for your problem.

The model is $x = h sin (k t + α)$ $x =h sin (kt+alpha)$ , where h and/or k $\to$ $to$ 0.
