Refractive index - Wikipedia
In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium. It is defined as =, where c is the speed of light in vacuum and v is the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1.333 times faster in vacuum than in the water....

Horizon - Wikipedia
However, ignoring the effect of atmospheric refraction, distance to the horizon from an observer close to the Earth's surface is about ≈, where d is in kilometres and h is height above ground level in metres. The constant 3.57 has units of km/m ½ Examples: For an observer standing on the ground with h = 1.70 metres (5 ft 7 in), the horizon is at a distance of 4.7 kilometres (2.9 mi)....
