WebDescription. ridx = refractiveidx (h) calculates the refractive index ridx at height h above mean sea level (MSL) using the International Telecommunication Union (ITU) standard atmospheric model. ridx = refractiveidx ( ___,Name,Value) calculates the refractive index with additional options specified by one or more name-value pairs. WebRefraction, quantified by Snell’s Law, is a consequence of the fact that as waves move through space their frequency remains constant. If a wave passes through a change in phase speed in the medium, its wavelength must change in order for frequency to remain constant. Let’s work with a concrete example. stanley gap trail georgia

"WebThe index is a relative index of refraction, the ratio between the interior and exterior index of refraction, where the exterior is defined by the direction of the normals (normals point away from the interior). In the case of total internal reflection, this function returns the reflection vector. For example: " - Refraction vector
