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

**A**
**E = n * h * ν**
**E/h = n *** **ν**

You should you the following energy equation:

h = Planck’s constant = 6.62607004 × 10^{-34} m^{2} kg / s

So, dividing the energy by Planck’s constant will give you the number of photons emitted per second.
