| Rate
of Photoelectron emission |
 |
| Intensity of light (Brightness) |
... but
not faster
(more energetic) electrons!!!!
| K.E. of Photoelectrons |

| Intensity of light (Brightness) |
Results
Contradict Wave theory!!
According to
wave theory…
Increasing Brightness,
Increases Energy of wave
|
|
 |
Should Increase Kinetic Energy
of Electrons Emitted
- It Didn't!!
