`lambda = c/f`

Enter a value for all fields

The **Wavelength of Light** equation is used to calculate the wavelength of light in a particular medium using the frequency and speed of light where:

- `f` = frequency
- `c` = speed of light

**Wavelength(**`lambda`**):** The equations returns the wavelength(`lambda`) in meters. However, this can be automatically converted to other wavelength units via the pull-down menu.
