# Wavelength calculation

This online calculator will help you calculate the wavelength based on the entered frequency. There are also additional calculation buttons, by clicking on which you will receive 1/2 wavelength and 1/4 wavelength. Ready-made calculations can be obtained in the metric system of calculation and English.

### For reference

Wavelength is the distance between two points in space closest to each other, at which oscillations occur in the same phase.

Light wavelength: 380-400 nm to 760-780 nm.

The wavelength on which popular radio stations broadcast: from 2.7 to 2.9 meters.

The wavelengths on which cellular operators work: from 35 cm (850 MHz) to 15 cm (1900 MHz).

The laser wavelength, depending on its type, starts from 400 nm to 760 nm.

All calculations are made using this calculator.
