The phase speed of waves is given by the following formula:

Speed of wave propagation, strength of materials.

Sometimes c is used for the speed of waves in any material medium, and c for the speed of light in vacuum.

Hence these can be used to determine the wavelength of monochromatic light as well as the speed of waves depending on wavelength.

Because of the speed of wave propagation through the diaphragm material, the center of the diaphragm moves slightly later than the perimeter.

This quickly elevated the height and increased the speed of waves, causing the complete destruction of the nearby Indonesian town of Lhoknga.

Replies: "The speed of waves propagating through a medium is determined not by the frequency or amplitude of the wave but by the properties of the medium."

Since the speed of waves in the Earth increases with increasing depth, the longer wavelength (low frequency) waves can travel faster than the shorter wavelength (high frequency) waves.

To model dispersive wave phenomena, those in which the speed of wave propagation varies with the frequency of the wave, the constant c is replaced by the phase velocity:

The stationary phase approximation states that for any speed of wave propagation determined from any distance and time , the dominant frequency of the precursor is the frequency whose group velocity equals :

The relative movement of the ether ought to have an effect on the speed of light passing through it, the theory went, just as the movement of water or air affects the speed of waves passing through them.

For example if the string speed were the same as the speed of wave propagation along the string, the wave moving opposite to the string motion would actually be stationary and the wave moving in the direction of the string would appear to move twice as fast.
