Description

technical field

[0001] The invention relates to a demonstration device, in particular to a physical convex lens experiment demonstration device. Background technique

[0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today.

[0003] Convex lenses are made according to the principle of refraction of light. Convex lenses are lenses that are thicker in the center and thinner at the edges. Convex lenses are divided into biconvex, plano-convex, concave-convex (or ...
