Sentences with phrase «photons of certain wavelengths»

Ordinary lasers work by bouncing light between two mirrors, so photons of a certain wavelength accumulate.

You also seem to think that a photon of a certain wavelength changes absorption characteristics depending on the temperature of its source.
