Abstract

The invention discloses an experiment device for solid refractive measurement. A light beam emitted by a semiconductor laser is radiated to a sheet-shaped solid sample through a polarization sheet; reflection light reflected by the solid sample is radiated to a long-sheet flexible solar battery and is converted to a voltage signal to output; the solid sample is placed on a rotary plate of an experiment chamber which is of a cylinder shape in order to change an incident angle of the light beam; a rotary encoder which is connected to the under of the rotary plate outputs angle information; and the solid refractivity index can be measured and the Fresnel law can be verified by cooperating with an analyzer, and the experiment device for solid refractive index measurement can be conducted in a light lab.

Description

technical field [0001] The invention belongs to a teaching experiment device, more specifically, it belongs to a solid refractive index measurement experiment device used in college physics experiments, and can verify Fresnel's law. Background technique [0002] When light waves pass through the interface of two uniform media, reflection and refraction will occur. At any time, the electric vectors of the incident wave and the reflected wave can be divided into two vectors, one parallel to the incident surface (indicated by P), and one perpendicular to the incident surface. Surface (denoted by S), according to Fresnel's law, in the form of propagation from optically thinner medium to optically denser medium: the reflection intensity of P light decreases gradually with the increase of the incident angle, and when it reaches a certain angle, it will There is a phenomenon that the reflected light intensity tends to zero (the actual experiment shows that the light intensity is th...
