Description

Light refraction demonstration device

Technical Field

The utility model relates to an optical equipment technical field especially relates to a light refraction presentation device.

Background

Light is an electromagnetic wave that has two components perpendicular to the direction of propagation during propagation: when the electric field component and each atom in the propagation process act, electronic polarization is caused, namely, the relative displacement of an electronic cloud and an atomic load center is caused, and the light refraction is that when the light obliquely enters another medium from one medium, the propagation direction is changed, so that the light is deflected at the junction of different media.

In real life, refraction and reflection phenomena of light often occur, for example, when fishing in a river, the position of the fish appearing in water is not the position of the real fish due to the refraction phenomenon of light; the chopsticks are put into a bowl containing water as if being broken off; the world outside from the pool appears to be elevated; the phenomena including mirage and the like are realistic examples of refraction and reflection of light, how to measure the refractive indexes of different liquids, the experimental instruments in schools and markets are simple, the refraction phenomenon of the light cannot be effectively demonstrated, the refractive index of the light is difficult to accurately calculate, although some instruments capable of measuring exist, the operation is complex, the calculation is complex, and the method is not suitable for accurately and quickly calculating the refractive index of a certain medium, so that a light refraction demonstration device is provided.
