What frequency of light of light has energy of 8.2x1019 j?

Answer 1

When you talk about the energy of any electromagnetic radiation in terms of its

frequency, you're talking about the energy of a single photon.

8.2 x 1019 J is a bit more than 1,000 times the energy that the Braidwood nuclear

generating station south of Chicago produces in a year.

In order for a single photon to have 8.2 x 1019 J of energy, its frequency would have to be

8.2 x 1019/Planck's Konstant = 8.2 x 1019/6.62608 x 10-34 = 1.2375 x 1053 Hz.

That's about 1034 times the frequency a photon needs in order to be called a

gamma-ray. At that frequency, the wavelength is about 2.422 x 10-45 meter,

and that's something like 10-27 the size of an electron.

Perhaps you meant to type 8.2 x 10minus 19 J.

The frequency of photon with that energy is

8.2 x 10-19/6.62608 x 10-34 = 1.238 x 1015 Hz.

and its wavelength is about 242 nanometers.

That would be a photon in the mid-range ultraviolet.

If you want a beam of light that carries your alleged 8.2 x 10plus 19 J,

you just need more of these photons ... like 1038 of them.
