Waves travel at different velocity in different medium. How does wave velocity effect wave frequency?

Solutions

Expert Solution

The wave velocity increases the wave frequency if the velocity is high. It also decreases the frequency if the wave velocity is low. This is because the higher the velocity, the higher the wavelength and vise versa.

When a mechanical wave (waves other than light/em radiation) is created, it must move through a medium. Through different mediums, waves travel at different speeds (depending on how rapidly the molecules/particles of the medium are moving and how close together they are). When a wave is created, it has a certain speed (depending on the medium) and its frequency depends on the resonant frequency of the source; so the wavelength depends on a combination of the two (using velocity=wavelength*frequency). When a wave passes through a new medium, the speed changes, because it depends on the medium, and the wavelength also changes because it depends on the other two. Frequency does not change in a change of mediums.

Summing up, the medium does not affect a waves frequency. The source is the only thing that determines it.
