Given:

Wavelelngth λ = 4.5 × 10−6 cm = 4.5 × 10−8 m

Speed of light c = 299,792,458 m/s.

Frequency f = c / λ = 299,792,458 m/s / 4.5 × 10−8 m = 6,662,054,622,222,222 Hz

= 6,6620 × 1014 Hz.

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

When you talk about the energy of any electromagnetic radiation in terms of itsfrequency, 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 nucleargenerating 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 be8.2 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 agamma-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 is8.2 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.
