Document Summary

The wavelength is a function of the temperature: the higher the temperature the shorter the wavelength. Radiation must be given out in quantities and not all at once as discovered by planck. A plate (chunk of metal) and you shine a light in a vacuum to contain electrons, a grid is a wire mesh and the electrons went straight through: when you turn the light off, no current. When you turn the light on, there was current. The higher frequencies, the electrons keep coming off: what you"re doing is you"re using the same light jus at different intensities. Einstein got the nobel prize for the theory of photoelectric effect. In circular orbits around the nucleus forever and the electrons in the orbit have certain energy. Once electrons enter an orbit, the energy must be below zero, you must add energy to get the energy out.
