What Is This Tool?
This tool converts wavelength values measured in nanometres (nm), a unit commonly used for electromagnetic waves in the optical and near-infrared spectrum, to frequency values expressed in kilohertz (kHz), a standard frequency unit for audio and radio waves. The conversion is based on the inverse relationship between wavelength and frequency mediated by the speed of light.
How to Use This Tool?

Direct conversion to kHz from nanometres yields extremely high values uncommon outside optical frequencies
Frequently Asked Questions
-
What units does this converter support?
-
It converts wavelength in nanometres (nm) to frequency in kilohertz (kHz).
-
Why are frequencies so large when converting from nanometres to kilohertz?
-
Because nanometres represent very small distances, the inverse relation with frequency produces extremely high values in kHz.
-
Is the speed of light assumed constant in this conversion?
-
Yes, the calculation assumes the speed of light in vacuum.
