One of the key features of Loudon's approach is his emphasis on the quantized nature of light. He shows that the energy of light is not continuous, but rather comes in discrete packets, or quanta, which are now known as photons. This quantization of light leads to a number of interesting and counterintuitive phenomena, such as the photoelectric effect and the Compton effect.
