Document Summary

Electronic structure of atoms: the electronic structure of an atom refers to the arrangement of electrons. The wave nature of light: visible light is a form of electromagnetic radiation or radiant energy. Radiation carries energy through space: electromagnetic radiation is characterized by its wave nature. (a) All waves have a characteristic wavelength (lambda) and amplitude. The frequency, v (greek nu) of a wave is the number of cycles that pass a point in one second. The units of v are hertz (1 hz = 1s-1) It is important to recognize that the electromagnetic spectrum extends well beyond what we can observe with our eyes: short wavelength = high energy. Quantized energy and photons: some of the experimental observations around the turn of the 20th century could not be explained by classical physics. Blackbody radiation: the emission of light from hot objects. The photoelectric effect: the emission of electrons from metal surfaces on which light shines.
