How to use it
- Enter wave speed and select its unit.
- Enter wavelength and choose m, cm or mm.
- Calculate to view frequency in Hz, kHz and MHz.
Frequency Calculator
Calculate frequency from wave speed and wavelength with f = v ÷ λ.

About the Frequency Calculator
This calculator finds the number of wave cycles per second from propagation speed and wavelength.
Formula and logic
Frequency is f = v ÷ λ after converting wave speed to meters per second and wavelength to meters.
Example
A wave speed of 343 m/s and wavelength of 0.343 m gives a frequency of 1,000 Hz.
Notes
The formula assumes a consistent propagation speed and wavelength for the medium and conditions under study.
