UnitConFrequency & Wavelength
Frequency and wavelength are inversely related through wave speed. For electromagnetic waves in vacuum, wavelength equals the speed of light divided by frequency, but sound uses the speed of sound in a medium instead. This converter helps compare radio, optical, and acoustic wave references. It is useful for students, engineers, and curious general users.

Frequently asked questions
Frequency and wavelength are inversely related when wave speed is fixed. If frequency goes up, wavelength goes down.
Visible light spans a very high frequency range compared with radio or sound. Exact values depend on color, with violet higher than red.
FM radio frequencies in the neighborhood of 100 MHz correspond to wavelengths of a few meters. That is why FM antennas are much larger than optical devices.
The speed of light in vacuum is about 299,792,458 meters per second. It is a fixed physical constant used in many wave calculations.
