What is the energy of an emitted flame with a wavelength of #6.5 * 10^-20# m?
we know that,
The wavelength is incredibly short!!! It is difficult to imagine how did they measure it!
Here you have a flame of quite short wavelength well beyond the gamma ray range!!!
If you want, I think, you could use Einstein's equation for the energy
and also frequecy is related to eavelength
giving an energy of:
