Problem: How can I calculate the number of photons emitted per second?

FREE Expert Solution

Recall that the energy of a photon (E) is given by:


E=hv (1)


where:

h = Planck’s constant (6.626 × 10–34 J • s)

v = frequency (in s–1)


We can rearrange the reaction to calculate photons per second:
