Historical Framework |
|
In the 1800's, some physicists noticed that a current could be obtained by shining light
at a metallic surface under the right conditions. In this section, we take a look at the historical
framework surrounding the observation of the experiments and early pioneers as well as Max Planck and his
seemingly unrelated idea of quantized energy.
Turn the light on to see what happens.
