However, until now, there is no dedicated device for measuring the refractive index of the medium
The relevant experiments designed in physics textbooks are not only too complicated in principle and method, but also rely on visual inspection for key links, which can easily lead to measurement errors

Abstract
The invention discloses a measuring device for a medium refractive index, wherein a glass container (1) is filled with a medium to be measured for the refractive index; a thin transparent cover plate (9) is covered on the upper mouth of the glass container (1); a fixing plate (6) is fixed on the longitudinal middle vertical plane of the glass container (1) and above the thin transparent cover plate (9) in an inclined way; a laser pen (5) is fixed on the fixing plate (6) in an inclined way based on an ensured incidence angle. When the glass container (1) is filled with the medium, the laser emitted from the laser pen (5) forms refractive light spots on the crossing line between one side face of the glass container (1) and the longitudinal middle vertical plane of the glass container (1) through the refraction of the medium, wherein the upper and lower positions of the refractive light spots for different mediums are different; suitable n values corresponding to a plurality of h values can be calculated according to the function relationship between the depth h of the refractive light spot and the medium refraction index, and the n values are marked on the right side face of the container (1) to form a transparent ruler (10), and the refractive index n of the medium can be meaured according to the positions of the refractive light spot on the transparent ruler (10).
Description
technical field [0001] The invention relates to a device for measuring the refractive index of a medium, in particular, it is suitable for the demonstration of light refraction and the experiment of measuring the refractive index of a medium in physics teaching. Background technique [0002] The refractive index of a medium relative to vacuum (or air) is called the absolute refractive index of the medium, or the refractive index of the medium for short. Refractive index is one of the important physical parameters of matter. The refractive index can not only reflect the deflection ability of the material to light, but also can be used to identify the material in reverse. Therefore, the measurement of the refractive index of the medium is one of the important contents of basic physical optics. However, until now, there is no dedicated device for measuring the refractive index of a medium. The relevant experiments designed in physics textbooks are not only too complicated in ...
