WebWhat is the energy in Joule of a photon with wavelength 5,500 Angstrom (green light)? SOLUTION: The energy of a photon depends on its frequency (and wavelength) as E = h = h c/ . Remembering that 1 Angstron is equal to 1x10 -10 meter, and using the value of the Plank constant "h" tabulated at page 111 of the book, we find E = 3.6x10 -19 Joule. WebThe result will be the joules of energy contained in the photons. In the example, we multiply by 12 photons: (1.9864748 × 10^-26 Hz)*12 photons = 2.38376976 × 10^-25 joules Cite this Article Did you find this page helpful? 👍 👎 References About the Author Find Your Next … incorporating lessons learned
