Terahertz to nanometers

Type a value in THz to get it in nm instantly.

545.1nm

That's 1.36× as long as violet light, while green light is 1.01× longer. That is visible light, carrying 2.275 eV per photon.

What it means

What color is that?

Wavelengths are for a vacuum. In glass or water light slows down and the wavelength shortens, while the frequency stays put.

The math

How to convert THz to nm

Wavelength, frequency and energy are linked by λ × f = c and E(eV) = 1239.84 ÷ λ(nm), so shorter waves carry more energy.

Example: 550 THz = 545.077 nm.
