Abstract

The invention discloses a teaching device for a light reflection experiment, and the device comprises a pedestal, a laser pen, a sliding frame, a medium, and a support for placing the medium. The pedestal is provided with an arc-shaped sliding rail with the central angle of 30-90 degrees. The sliding frame is slidingly disposed on the sliding rail, and the laser pen is fixed on the sliding frame.The support is fixed at one side of the pedestal, and the medium is placed on the support. The pedestal is provided with a first scale for measuring the incident angle and a reflection angle of light.Through the above setting, a student does not need to manually make a related experiment instrument, and can complete the experiment through an existing instrument, thereby saving the time of the student in making the instrument, solving a problem that a student with the poor manual ability cannot complete the making of the instrument, and enabling the student to participate in the experiment ina better way and to learn the corresponding knowledge.

Description

technical field [0001] The invention relates to a teaching device, more specifically to a teaching device for light reflection experiments. Background technique [0002] People can see non-luminous objects because of the reflection of light. In physics, the reflection of light is an important lesson. The combination of experimental teaching can enable students to better grasp the relevant knowledge. In the existing courses, students are required to shine a flashlight on a paper tube with a round hole to generate light, and then students are required to measure the angle of the light correctly. Students have different hands-on abilities, and students with poor hands-on ability cannot complete the production of related appliances within the course time, so they cannot complete related experiments. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a teaching device for light reflection experime...
