[0002] The refraction of light is that when light is obliquely incident from one transparent medium into another transparent medium, the propagation direction will generally change. This phenomenon is called the refraction of light. In the process of teaching light refraction, it is usually through teaching and drawing Forms to enable students to understand and learn, not to give students a specific understanding through specific demonstrations, which increases the difficulty of learning

Description
technical field [0001] The invention relates to the technical field of teaching aids, in particular to a light refraction demonstration device. Background technique [0002] The refraction of light is that when light is obliquely incident from one transparent medium into another transparent medium, the propagation direction will generally change. This phenomenon is called the refraction of light. In the process of teaching light refraction, it is usually through teaching and drawing. Forms are used to enable students to understand and learn, and students cannot have a specific understanding through specific demonstrations, which increases the difficulty of learning. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a light refraction demonstration device, which has a simple structure and good stability, and can demonstrate and draw the route of light transmission, which can effecti...
