The energy of a photon is given by the equation:

E = h * f

where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon.

Plugging in the given frequency of 5 × 10^20 Hz, and using the value of Planck's constant h = 6.626 x 10^-34 joule seconds, we get:

E = (6.626 x 10^-34 J s) * (5 x 10^20 Hz) = 3.313 x 10^-13 joules

Therefore, the energy of a photon with a frequency of 5 × 10^20 Hz is approximately 3.313 x 10^-13 joules.
