Question

The velocity of a wave is primarily determined by the

Answer 1

Answer: medium  

The propagation velocity of a wave depends on the medium in which it propagates.  

In addition, it depends on the type of wave, for example a mechanical or electromagnetic wave.  

In any case, the velocity of a wave is generally related to the value of the wavelength and the period, and can be expressed mathematically through the following formula:  

$v=\frac{\lambda}{T}$

where $v$ is the velocity of the wave, $\lambda$ is the wavelength and $T$ is the period.

Therefore:

The propagation velocity of a wave depends on the medium
