Spectrometer JJY1'-A/JJY1'-B

Experiment content:
Angle measurement in light reflection, refraction, diffraction, interference. Measure the top angle of the prism (optional low-pressure sodium lamp power supply). Measure the minimum deviation angle of the triangular prism (optional low-pressure sodium lamp power supply) and measure the grating constant (optional low-pressure mercury lamp point source)
A variety of experimental devices can be selected for a variety of experiments (such as the measurement of the refractive index of liquid solids, the measurement of the speed of sound, the measurement of polarized light, etc.).
