Web13. apr 2015 · To convince yourself of this, imagine the limiting case where you measure index of refraction of air as the pressure is gradually lowered. When it gets to 0, the index of refraction must be 1 by definition. The index of refraction of air therefore varies smoothly as a function of pressure. Now think of the air envelope around the earth. dva fenjera mostarWeb24. jan 2024 · Refraction occurs when light passes from one environment to another.
