Imaging and Measurement of Thermal Lensing in Glass
... The observed photoelectric effect led to a similar problem. When bombarding certain metals with light, electrons would be emitted with a maximum energy that was measured as a voltage. This maximum kinetic energy was not dependent on the intensity of the incident light as classical models would have ...

The molecule is therefore an oscillating charge dipole and, if it is spherically symmetric, we expect the amplitude of oscillation of the electrons to be independent of the direction of the incoming electric field. According to electromagnetic theory, the oscillating dipole must itself radiate light ...
