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 = hvE=hv

Explanation:

In the formula E =hvE=hv:

EE is the energy in Joules
hh is Planck's Constant and
vv is the frequency of the photon (light)

So therefore the Energy of a photon with a frequency of 8*10^1381013 Hz will be:

E = hvE=hv
E = 6.626*10^(-34)E=6.6261034 m^2m2.kgkg/ss x 8*10^1381013 Hz
E = 5.3*10^-20E=5.31020 Joules

Therefore the energy of the photon is 5.3*10^-205.31020 Joules

Hope I helped :)
