Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric effect experiments, in particular to a photoelectric effect test experimental device. Background Art

[0002] The photoelectric effect experiment is an experimental method used to verify the photoelectric effect phenomenon. Its principle is that when light is irradiated on the surface of metal or semiconductor, the energy of photons can be absorbed by electrons, and the electrons jump from the bound state to the free state, forming electron-hole pairs. If an appropriate electric field is applied, the electrons will be affected by the electric field force, thereby generating current. The light source is an adjustable monochromatic light source, so that the effect of different wavelengths of light on the photoelectric effect can be studied by changing the wavelength of light.

[0003] In the photoelectric effect experiment, the staff conducts the photoelectric effect experiment by replacing different color filters. The existing replacement method is to replace a single color filter and install it on the filter for the experiment. The color filter is easily worn and damaged during the installation process, which makes the photoelectric effect experiment data inaccurate. In addition, frequent replacement may cause the color filter to fall and break, resulting in the inability to conduct the photoelectric experiment normally, reducing the experimental efficiency of the photoelectric effect.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
