Description

technical field [0001] The invention belongs to the technical field of optical teaching and demonstration experimental instruments, and in particular relates to an experimental demonstration device for the relationship between fluid refractive index and temperature. Background technique [0002] The change law of atmospheric refractive index with the distribution of atmospheric temperature is the basic content of atmospheric optics. Studies have shown that the atmosphere, as a continuous medium, has a refractive index that is a function of temperature, mainly because the temperature distribution in the air directly determines the density distribution, and the density of the medium is directly related to the refractive index. The refractive index is small. Therefore, the refractive index of the low-temperature region of the atmosphere is greater than that of the high-temperature region. This law makes the light beam bend and transmit to the low-temperature region of the atmo...
