Abstract

The invention discloses a physics light refraction experiment teaching device, including a device placement chamber and a chassis, A accumulator is arrange on that top of one side of the placing chamber of the device, A suction vacuum pump is arrange on one side of that bottom of the placing chamber of the device, A chassis is arranged on one side of the placing cavity of the device, the air suction hole is arranged at the bottom of one side of the chassis, three laser lamps are arranged on the top of one side of the chassis through a clasp, three dials are uniformly arranged in the middle ofone side of the chassis, the three dials are sequentially provided with water tanks from one side to the other side, Air tank and glass tank, A light absorbing layer is arranged at the bottom of the transparent glass cover, A light refraction experiment teach device Three refractive grooves are arranged on the chassis, which can conveniently compare the refractive effects of different media on thelight, and the scale on the dial is convenient to calculate the refractive index. The vacuum pumping machine can pump the air out of the device to prevent the influence of the air on the experimentalresults, and the light-absorbing cloth layer can reduce the harm of light pollution to people.

Description

technical field [0001] The invention relates to a teaching appliance, in particular to a teaching appliance for a physical light refraction experiment, belonging to the technical field of teaching appliances. Background technique [0002] When light is obliquely incident from one medium into another medium, the direction of propagation changes, so that the light is deflected at the junction of different media. The refraction of light, like the reflection of light, occurs at the junction of two media. It's just that the reflected light goes back to the original medium, and the refracted light goes into another medium. [0003] The existing experimental device is to hold a laser pointer and an optical sample when coming, and measure it with an angle ruler. On the one hand, it is inconvenient to control the light irradiation manually, and it is not possible to conduct a control experiment on the experiment. The measurement result is not intuitive enough and it is easy to cause ...
