WebWhen a WS-1 or WS-1-SL is used as the standard in a reflectance measurement, OceanView essentially defines its reflectivity as 100%. The relative reflectivity spectrum is accurate … In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors. For example, it is used in optics to calculate the amount of light that is reflected from a surface with a different index of refraction, such as a glass surface, or in an electrical transmissi…
