WebOct 23, 2024 · For long distances (> 1 km), which is mostly the case of landslide deformation monitoring in mountainous areas, it is necessary to compute more rigorously the atmospheric contribution on the... WebAtmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near the …

Consequently, so are the angle of refraction and the wave-vector. This implies that, while … See more Ptolemy, in Alexandria, Egypt, had found a relationship regarding refraction angles, but it was inaccurate for angles that were not small. Ptolemy was confident he had found an accurate empirical law, partially as a result of slightly altering his data to fit theory (see: See more Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labeled $${\displaystyle n_{1}}$$, $${\displaystyle n_{2}}$$ and so on, are used to represent … See more In many wave-propagation media, wave velocity changes with frequency or wavelength of the waves; this is true of light propagation in most transparent substances other than a vacuum. These media are called dispersive.
