- The speed (or sometimes you might see it called velocity) of a wave ( (v)) is how far the wave travels in a certain time. Wave speed is measured in metres per second ( (m,s^ {-1})). All the electromagnetic waves travel at 300,000,000 metres per second ( (3times 10^ {8},m,s^ {-1})). Sound travels at about 340 metres per second.

In seismology and other areas involving elastic waves, S waves, secondary waves, or shear waves (sometimes called elastic S waves) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.
The speed (or sometimes you might see it called velocity) of a wave (\(v\)) is how far the wave travels in a certain time. Wave speed is measured in metres per second (\(m\,s^{-1}\)).

Like the speed of any object, the speed of a wave refers to the distance that a crest (or trough) of a wave travels per unit of time. But what factors affect the speed of a wave. In this Lesson, the Physics Classroom provides an surprising answer.
P-waves have speeds of 4 to 7 km/s, and S-waves have speeds of 2 to 5 km/s, but both are faster in more rigid materials. The P-wave gets progressively farther ahead of the S-wave as they travel through Earth’s crust.

The wave speed is the distance traveled per time ratio. But wave speed can also be calculated as the product of frequency and wavelength. In this Lesson, the why and the how are explained.
