Document Summary
All oscillating systems of natural frequency f have discrete allowed energies. The smallest change in energy of the system is given by. Minimun change in energy. u (f, t)df u (f, t)df. Continuous spectrum of the blackbody: the heated walls contained resonators vibrating at many different frequencies, each emitting light at the same frequency as its vibration frequency. (f, t) u (f)n. Calculated in a discrete set of quantum oscillator energies. Rayleigh-jeans law in a continues distribution of classical oscillator energies. is independent of frequency. Allows only discrete values of energy for a resonator. u hf/(e (f, t)df. Light quantization and the photoelectric effect hf/k tb 1. * v m v oltage) e 2max = ev (electron charge. : increases with light frequency. does not depend on intensity of exciting light. Clean metal surfaces emit charges when exposed to ultraviolet light. Energy of light is concentrated in discrete regions call quanta.
