- depending upon the metal and the frequency of light used,<br />
electrons were emitted by the cathode and traveled to the<br />
anode, generating a current measured by the ammeter<br />
- the higher the frequency used, the greater the velocity and KE<br />
the ejected electron would have<br />
- experiments showed that the frequency of light used had to be at<br />
a minimal level or higher to eject electrons from the surface<br />
of the cathode; (threshold frequency)<br />
- this threshold frequency varied depending on what type of metal<br />
was used
