Question

Approximately how far does a p wave travel in 8 minutes

Answer 1

where K is the modulus of incompressibility, μ is the modulus of rigidity and ρ the density of the material through which the wave is propagating

Of these density shows the least variation so the velocity is mostly controlled by K and μ.

The elastic moduli P-wave modulus, M, is defined so that M = K + 4μ / 3 and thereby .

Typical values for the velocity are in the range 5 to 8 km/s
