Velocity+of+propagation

By Kiefer Timmann Velocity of Propagation is a parameter that characterizes the speed at which an electrical signal passes through a [|medium]. It is a vector quantity. It measures the direction and speed when a wave travels through a medium.

Velocity of Propagation = λ (wavelength) x //f// (frequency)

Velocity of propagation is a vector quantity. It is a measure of the direction and speed at which a wave travels through a medium. The speed of propagation is dependant only on the medium itself. All waves which travel through a given medium (regardless of frequency, amplitude and source) will propagate at the same speed. For example, the “speed of sound” (334 m/s or about 770 mph) is the speed of propagation of sound waves in air. All sound waves travel at that same speed in air. Note: sound waves can propagate through different mediums other than air. The velocity of propagation in other media will be different than that in air. The direction of propagation is also a function of the medium and is independent of the wave. In a one dimensional medium like a string, waves will propagate in one dimension along the string. In a two dimensional medium like the surface of a pool of water, waves will propagate in two dimensions spreading out over the surface. In a three dimensional medium like air, waves will propagate in three dimensions spreading out in all directions.
