This product is used for elementary and high school to demonstrate the dispersion of white light and the phenomenon of the synthesis of white light from seven colors. The product consists of two prisms with an apex angle of 60°, a prism table, and a light source. Dispersion: The light source of this instrument is powered by the student's power supply. After the bulb is lit, move the lens left and right until a clear filament image appears in the center of the screen. At this time, fix the lens and place a prism on the prism holder (note the prism and the prism Contour lines coincide) During the experiment, rotate the prism table slightly so that the angle of the incident light on the incident of the prism is about 57°. At this time, in the direction deviated from the optical axis by about 54°, the light screen can be used to receive red, orange, yellow, green, The spectrum band composed of the seven colors of blue, cyan, and purple can also be directly projected on the wall. Synthesis: Install another prism on the prism stand. When placing the prism, pay attention to the direction of the apex angle of the prism opposite to the first one. The seven colors of white light decomposed by the first prism are combined into white light, and the white light image of the slit can be received in the direction of the incident light. It is as if the light passes through a very thick parallel glass, it shifts.
