Photonenergie

Relate photon wavelength to energy using exact SI defining constants.

Mat der Iddi ufänken

Dës Säit fänkt mat der Iddi un, net mat der Formel. Kuckt fir d'éischt wat gemooss gëtt, wéi eng Eenheeten dobäi sinn a wat sech ännert.

E = hc/λ

Referenz constant used by this model where applicable: 6.62607015e-34. Keep SI units consistent before interpreting a numerical result.

Input A is wavelength in nanometres; result is joules per photon.

Before trusting the result, ask whether the units and order of magnitude make sense. A calculator cannot rescue a wrong physical model.
