The study of light interference and diffraction helps to further deepen the understanding of the volatility of light, but also helps to further study the modern optical experimental techniques, such as spectral analysis, crystal structure analysis, holography, optical information processing.

Comprehensive Microwave Optics System

The comprehensive microwave (MW) optics system studies the wave characteristics of MW, e.g., diffraction, interference and polarization.
MW is an electromagnetic wave (range of 300Mz-3000GHz) emitted from a signal source, passes through single/two slits and polarizing plates, and is received by a receiver.
By studying the diffraction, interference, and polarization images of the MW, the wave characteristics of MW can be testified.

Photoelectric Effect Experiment

The photoelectric effect experiment adopts high-pressure mercury lamps as the light source. The five characteristic spectrallines (365nm, 405nm, 436nm, 546, 577nm) are filtered by an interference filter and aperture (2mm, 4mm, or 8mm) and turned into narrowband monochromatic light of fixed spot size.
With the DC voltage between the anode and cathode, the monochromatic light shone on thephototube induces photocurrent, which is then amplified by a micro-current amplifier and can be measured.
By studying the relationshipsamong wavelengths, aperture size, and light intensity, Einstein's photoelectric effect theory can be verified.
