Photoelectric Effect – 7A10.00
h/e Stopping Potential – 7A10.30
- Filters (450, 500, 550, 600, 650 nm) are placed on a light source shining on a PASCO phototube.
- Connected to the apparatus is a voltmeter which displays the stopping potential for a given wavelength of light.
- Values of h can be measured within a percent or two.
