Ultraviolet 3 x 103 1 x 1015 X-rays 1 3 x 1018 Electronic Gamma rays 10-2 3 x 1020 Cosmic rays 10-4 3 x 1022 Nuclear transitions The propagation of these radiations involves both electric and magnetic forces which give rise to their common class name electromagnetic radiation. In spectroscopy, only the effects associated
