WebWhere the refraction angle is large, and not near to zero as it is in the case of reflection work, there are many considerations concerning the geometry of the ray-path that have to be made in refraction interpretation. WebMay 1, 2024 · Many researchers have used seismic refraction in quarry/mining studies. Kausarian et al. (2014) conducted seismic refraction survey to characterize rock mass at a quarry. Results obtained have shown there are five zones of weathered granite, which was divided by the range of refractive wave velocity (Vp). Vp has a certain range of velocities ...

WebDec 17, 2024 · The ratio of sine of angle of incidence and the sine of angle of refraction is a constant for light of a given color passing through the same pair of materials. This law is also known as Snell's law of refraction. If θ i is the angle of incidence and θ r is the angle of refraction, then, sin. . θ i sin. .
