Optical experiment demonstration structure applied to physics teaching

Abstract

The invention belongs to the technical field of application of teaching apparatuses, and specifically discloses an optical experiment demonstration structure applied to physics teaching. The structureis formed by a bottom elevation adjustment assembly and a refraction demonstration assembly used in cooperation with the bottom elevation adjustment assembly. The beneficial effects of the optical experiment demonstration structure applied to physics teaching are that the design structure is reasonable, certain height adjustment can be performed through an inner spiral adjusting sleeve, an auxiliary outside thread adjusting column and a positioning screw rod during demonstration, if a requirement is not met, height adjustment is performed again through a first thread adjusting hole, a secondthread adjusting hole, a first elevation adjusting screw rod and a second elevation adjusting screw rod, stable limitation of the incident angle for a small electric torch of a light-emitting source can be performed through additionally provided components including an arc groove, first auxiliary internal thread positioning holes, a second auxiliary internal thread positioning hole and an auxiliary positioning screw rod, the unity of the demonstration incident angle is improved, high-efficiency teaching demonstration effect can be guaranteed, and the teaching quality is improved.

Description

technical field [0001] The invention belongs to the technical field of teaching instrument application, and specifically relates to an optical experiment demonstration structure applied to physics teaching, which is suitable for physics teaching demonstration operations, realizes efficient and stable light reflection teaching, and at the same time facilitates intuitive demonstration and observation and improves student performance. Learning enthusiasm, learning efficiency, improve teaching quality. Background technique [0002] Light reflection is a physical phenomenon in nature. When light hits the interface between two media, some of the light changes its propagation direction and returns to the original medium to continue to propagate. This light reflection phenomenon is called light reflection. [0003] The phenomenon of reflection of light is universal. When light hits the surface of any object, reflection will occur (except for the absolute black body, which can absorb...

Problems solved by technology

[0006] Purpose of the invention: the purpose of the present invention is to provide a kind of optical experiment demonstration structure that is applied to physics teaching, and its design structure is reasonable, can carry out certain height adjustment through internal screw adjustment sleeve, auxiliary external thread adjustment column, positioning screw rod during demonstration, if If it fails to meet the requirements, adjust the height again through the first thread adjustment hole, the second thread adjustment hole, the first lift adjustment screw, and the second lift adjustment screw to solve the problem that the height of the existing demonstrator cannot be adjusted, and the increased arc Shaped groove, the first auxiliary internal thread positioning hole, the second auxiliary internal thread positioning hole, and auxiliary positioning screw can stably limit the incident angle of the small flashlight of the light source, improve the uniformity of the incident angle of the demonstration, and solve the current problem. There is a problem that the light source of the demonstrator cannot be fixed, ensuring efficient teaching demonstration effects and improving teaching quality
