WebSpectral reflectance is the ratio of reflected energy to incident radiation ... 0.86 μm) where both the reflectance and transmittance are low. The transmittance of visible radiation through water implies that if depth is shallow, the radiation is reflected by the bottom of the water body, transmitted back through the water, and detected by the ... WebWhen a person views an object, light from a light source that is reflected from the object (or passes through the object) enters the eye and is collected by several types of photoreceptor cells in the retina. The proportion of light collected by these cells is sent to the brain and sensed as color.
WebSince the circuit parameters correspond to (1) reflectance at the interface between layers, (2) phase retardation, and (3) attenuation with passage through the layer, the instrument can treat problems involving oblique as well as normal incidence, polarization, and absorption. © 1954 Optical Society of America Full Article PDF Article Web28. sep 2024 · Multiplying the transmittance by 100 gives the percent transmittance, %T, which varies between 100% (no absorption) and 0% (complete absorption).
