How would you calculate the energy of a photon with a known frequency?

For example, if the frequency is "8x10^13Hz"

The energy of the photon can be calculated using E=hv

Explanation:

In the formula E=hv:

E is the energy in Joules
h is Planck's Constant and
v is the frequency of the photon (light)

So therefore the Energy of a photon with a frequency of 81013 Hz will be:

E=hv
E=6.6261034 m2.kg/s x 81013 Hz
E=5.31020 Joules

Therefore the energy of the photon is 5.31020 Joules

Hope I helped :)
