Table 6: Stopping Potential of Spectral Lines, 4 mm diameter Aperture
The next two tables show typical data for Stopping Potential of Spectral Lines for the 2 mm and 8
mm diameter apertures.
Table 7: Stopping Potential of Spectral Lines, 2 mm diameter Aperture
Table 8: Stopping Potential of Spectral Lines, 8 mm diameter Aperture
Experiment 2: Measuring Current-Voltage Characteristics of Spectral Lines -
Constant Frequency, Different Intensity
The illustration shows typical data for
current versus voltage for a single spectral
line (435.8 nm) with three different
apertures.
The next table shows typical data for current
versus voltage for a constant frequency and
three different apertures.
