WebSo let me just substitute. If we substitute we get three times 10 to the power eight, that's the speed of light in vacuum, meters per second, divided by one point five. Refractive index by the way has no units. And if you divide it, see what you get. You get three divided by one point five so we get two times, three by one point five is two ... WebRefraction is the term used for the bending of radio waves. In outer space, with no atmosphere, radio waves propagate in straight lines. In the earth's troposphere, radio waves are bent, due to interactions with the bounded electrons in air molecules. ... and use this to create a simple formula for determining the range to the radio horizon: d ...

Snell's law (also known as Snell–Descartes law and ibn-Sahl law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
