Einstein's
photoelectric effect equation, the photon: it was the other research
direction is: how the impact of light on things? Most of the results of
an object to increase the absorption of light energy (heat). One of
them accidentally found: high-frequency ultraviolet light hit certain
metals, there will be electronic ran out, this is the photoelectric
effect. More unexpected is that this is not a simple energy transfer.
Because (1) If the low-frequency light, no matter how strong light,
long exposure time there is no such effect. (2) If the frequency
exceeds a certain value, this effect will appear immediately. Increase
in light intensity can increase in the number of electronic run out,
but does not affect the energy of each electron. |
