Frequently Asked Questions

What does converting wavelength in nanometres to millihertz tell me?
It translates the spatial measurement of an electromagnetic wave’s wavelength into its frequency expressed in millihertz, illustrating their inverse relationship.

Why is the conversion factor between nm and mHz so large?
Because frequency is inversely related to wavelength and the units involve very different scales, the conversion factor reflects this inverse proportionality and scale difference.

Can I use this conversion for waves traveling through materials other than vacuum?
No, this conversion assumes propagation in vacuum and does not consider refractive index changes that affect effective frequency.

Key Terminology

Wavelength in nanometres [nm]
The distance between successive peaks of an electromagnetic wave, measured in nanometres, commonly used for optical and near-infrared radiation.
Millihertz [mHz]
A frequency unit equal to one thousandth of a hertz, used to describe very low-frequency oscillations.
Frequency
The number of cycles or oscillations of a wave per second, inversely related to its wavelength in vacuum.
