On the other hand if the crest of an ocean wave moves a distance of 25 meters in 10 seconds the same amount of time then the speed of this ocean wave is 25 ms. Sound travels faster through liquids and solids than it does through air and other gases. P-waves have speeds of 4 to 7 kms and S-waves have speeds of 2 to 5 kms but both are faster in more rigid materials.
Wave speed v is measured in metres per second ms frequency f.
Refer to the Earthquake Time Travel Graph. Lets take for instance the case of a wave with a frequency of 56 Hz going through a material at a speed of 168 ms. A2 l 2µr v2 µr r is the density of the material through which the wave propagates. Shear modulus pascal r.
