4:447:25Light: number of photons problem – YouTubeYouTubeStart of suggested clipEnd of suggested clipTotal is equal to the energy of a single photon. E1 times the number of photons. So since all theMoreTotal is equal to the energy of a single photon. E1 times the number of photons. So since all the photons are exactly the same energy to get their total energy we multiply the number of the photons.

And then the number of photons equal to the total energy of the light, which is 637 kg jewels or tents on the three jewels, times 3.37 times 10 to the minus 19 jewels per photon. And this would give us 1.89 Times 10 to the 24th Photons. So this would be our answer. 1.89 times 10 to the 24th photons would be released.
How many photons are in a blue light?
In a paper published in the journal Science, researchers led by Marco Ajello from the Clemson College of Science in South Carolina, US, report that the total number of photons produced in the 13.7 billion years since the Big Bang is 4×1084.
How do you calculate photons?
According to the equation E=n⋅h⋅ν (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. Eh=n⋅ν → the term n⋅ν should have units of photons/second.
How do you calculate the photon?
Photons velocity equals the speed of light. Photons are massless, but they have energy E = hf = hc/λ. Here h = 6.626*10-34 Js is called Planck's constant. The photon energy is inversely proportional to the wavelength of the electromagnetic wave.
