Cobalt-60 is an artificial radioisotope that is produced in a nuclear reactor and is used as a gamma-ray source in the treatment of certain types of cancer. If the wavelength of the gamma radiation from a cobalt-60 source is 1.00 x 10-3 nm. , calculate the quantum of energy of this radiation. Show all your work and include units.
wavelength x frequency = speed of light (speed of light = 3.00 x 108 m/s)
energy = Planck's constant x frequency ( Planck's constant = 6.626 x 10-34 J s)
