Problems solved by technology

[0002] In the middle school "Science" course teaching, there is a part of the content of physical optics: the linear propagation of light, the law of light reflection and the law of refraction. It is almost invisible and cannot show the route through which light passes, so the teaching is not intuitive, and students lack perceptual understanding of this part of knowledge
At present, some people try to make some backgrounds to set off the light, but it is always difficult to achieve the desired effect

Embodiment Construction

[0014] Referring to Fig. 1, under specific conditions (such as high temperature), select the liquid that has good transparency and can form a transparent solid at normal temperature, such as the liquid plexiglass material at high temperature; select reflective powder that is insoluble in this liquid, The reflective powder is made of materials with good light-reflecting characteristics, and it should be fine enough, preferably as the size of dust that floats up when wiping the chalk on the blackboard in teaching. Mix the reflective powder with the transparent liquid, let the reflective powder evenly distribute in the liquid and solidify into a transparent display panel 4, the amount of reflective powder should be moderate, too much will block the light and affect the light transmittance, too little reflected light will be Less, affect the brightness of the light.

[0015] Referring to Fig. 2, the reflection demonstration frame is composed of a frame background 1 and a frame bot...

Abstract

The present invention provides a light path display combination, especially a device of showing light path. The device belongs to the teaching laboratory equipment, characterized in that it is composed of a display board and a demonstration frame, when beam passes the display board composed by reflecting powder and transparent solid, the light path is shown, directly showing the straight propagation, reflection and refraction discipline of light, it is convenient for laboratory observation.

Description

technical field [0001] The invention relates to an optical path display combination, in particular to a device capable of displaying the path through which light passes. It belongs to teaching experiment equipment. Background technique [0002] In the middle school "Science" course teaching, there is a part of the content of physical optics: the linear propagation of light, the law of light reflection and the law of refraction. It is almost invisible and cannot show the route through which light passes, so the teaching is not intuitive, and students lack perceptual understanding of this part of knowledge. At present, some people try to make some backgrounds to set off the light, but it is always difficult to achieve the desired effect. Contents of the invention [0003] The object of the present invention is to provide a device that can display the light path conveniently and intuitively in the light path teaching. [0004] The present invention is achieved like this. ...
