Intensity of a photon

Nettet20. feb. 2024 · The energy of a photon is given by E = hf = hc λ. Using hc = 1240eV ⋅ nm, we find that E = hc λ = 1240eV ⋅ nm 100nm = 12.4eV. Discussion According to Table 29.3.1, this photon energy might be able to ionize an atom or molecule, and it is about what is needed to break up a tightly bound molecule, since they are bound by … NettetPhoton intensity received may vary with latitude, season, cloudiness, humidity, and even the atmospheric CO 2 level. Before reaching Earth’s surface, a significant portion of solar radiation (yellow region of Fig. 6 ) will be firstly absorbed by humidity and CO 2 in the air.

Light Intensity and Number of Photons Physics Forums

Nettet15. okt. 2024 · Number of photons per unit area is proportional to intensity. That’s because intensity = power/area = (energy/time)/area. A photon has energy h ν, where ν is the frequency. So intensity is N h ν / (time x area), where N is the number of photons.
