How many photons per joule

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. Web31 jul. 2024 · there are 1.64×10¹⁹ photons being emitted every second. Explanation: The 80W light bulb gives off 80 Joules a second. 8% of 80 J = 6.4 Joules. So every second 6.4 joules of light energy is given off. h = 6.626068*10^-34 ..................... (planck's constant ) c = 2.99792458*10^8.................... (the speed of light) L=510nm= 5.1*10^-7 metres.
