The alkali metals have work functions such that the photoelectric effect is seen at the frequencies (or wavelengths) of visible light. For accurate results, the measurement of very small photocurrents is required. The electronics and ammeter to do this are all contained in the “Photoelectric Effect” apparatus by Daedelon Corp. Theory of ...

The collector is a circular wire constructed so that a light beam can hit the center of the emitter without also hitting the collector. If light does hit the collector, then the photoelectric effect can also occur at the collector, resulting in a backward current in the tube which can distort the results of the experiment.

The photoelectric effect is one of the key experiments that supported early quantum theory. Light, prior to the early 20th century, was considered to be a wave phenomenon. In most ways, this idea reflects reality well—for instance, light is bendable when passed through a lens.
