E = hυ (this energy corresponds to the energy of one photon; the energy calculated in this problem is for one mole of photons so we will change this after we change the units from kJ to J). 8.20 x 10-5 kJ/mol photons = 1.36 x 10-25 J/photon. E = hυ. Rearranged: υ = E/h. υ = …

6. 1.02 MeV. The photon has to create the rest energy of two particles, each 0.51 MeV. 7. Approximately 104 pairs. Each pair requires approximately 1 MeV = 1 106 eV and 10 GeV = 10 109 eV is available. 8. The 1.28 MeV photon has enough energy to create an electron–positron pair.

May 04, 2015 · But (strangely) electromagnetic radiation also behaves like a stream of particles called photons. Each photon is a “packet” of electromagnetic energy. The energy of each photon is directly proportional to its frequency and inversely proportional to its wavelength and can be calculated using the formula: E. photon = hf = hc/ . The constant of proportionality, h, is called “Planck’s Constant” and is …

The energy of each photon is related to the difference in energy of the two levels. To measure the energy difference, measure the potential difference across the LED when it just glows. Then we multiply this figure by the charge on the electron (1.6 10–19 C).
