Wave Speed vs Frequency
Formula
## Wave Speed Wave speed links the spatial and temporal characteristics of any periodic wave. ### Formula **v = f * lambda** where *f* is the number of oscillations per second and *lambda* is the distance between successive crests. This relationship holds for sound waves, light, water waves, and all other periodic disturbances.
Esempio Risolto
A sound wave with frequency 440 Hz and wavelength 0.78 m.
- 01v = f * lambda
- 02v = 440 * 0.78
- 03v = 343.2 m/s

Does wave speed depend on amplitude?
For most linear waves, no. Wave speed depends on the medium properties, not the amplitude of the disturbance.
What determines the speed of sound in air?
Primarily the temperature. At 20 degrees Celsius, the speed of sound in dry air is approximately 343 m/s.
Is this formula valid for light?
Yes. For light in a vacuum, v = c = f * lambda, where c is approximately 3 x 10^8 m/s.
