| Abstract: | The refractive index of air is measured under different pressure using a self-established Mach-Zehnder interferometer,the relationship between refractive index and pressure change under constant temperature is obtained theoretically,the cause of refraction of light by air is analyzed and the experimental results are explained better. |
