Wave velocity

Wave velocity is the speed at which a wave propagates through a medium. It is calculated as the product of the wave's frequency and wavelength.

congrats on reading the definition of wave velocity. now let's actually learn it.

Wave velocity ($v$) can be expressed as $v = f \cdot \lambda$, where $f$ is frequency and $\lambda$ is wavelength.
In a given medium, wave velocity remains constant for a specific type of wave.
The speed of sound in air at room temperature is approximately 343 m/s.
Wave velocity can differ based on the medium; for example, light travels faster in a vacuum than in any other medium.
For transverse waves on a string, wave velocity depends on the tension and linear density of the string.
