Problem: The y-ray photons emitted by the nuclear decay of a technetium-99 atom used in radiopharmaceuticals have an energy of 140.511keV. Calculate the wavelength of these y-rays.
The solution manual says that in order to convert eV to Joules we have to multiply the eV by 1.6022*10^-19.
I was wondering if this is a constant that we have to memorize or where this number came from.
Thanks!
