WebAug 21, 2024 · The quantity on the left is a reciprocal length and the quantity on the right is an energy. It makes as much sense to say that they are equal as to ask whether the surface area of Europe is bigger or smaller than the mass of the Moon. What you can say is that, if a beam of light has wavenumber $\kappa$, then. its wavelength is $\lambda=1/\kappa$, WebThe visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. [1] In terms of frequency, this corresponds to a band in the ...
