Calibrate a monochrometer with light beams of known
wavelength. Measure the maximum energy of electrons
emitted from a photocathode as a function of incident photon wavelength
(energy). This energy is determined directly from the stopping potential as the
electrons charge up an anode.
This is a look at the
inside of
the monochrometer with the light path drawn.
The entrance
slit, the diffraction grating and the detector are also shown in the
picture on the left.
