1. Reflectance

   The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in general a function of the frequency, or wavelength, of the light, its polarization, and the angle of incidence. The dependence of reflectance on the wavelength is called a reflectance spectrum or spectral reflectance curve.

1. reflectance

   Reflectance is a physical property that quantifies the proportion of light or other electromagnetic radiation that is reflected by a surface, typically measured as a function of incident wavelength. The reflectance is expressed as a ratio or percentage, relative to a standard reference material. It can range from 0% (no reflection) to 100% (total reflection).

Examples of reflectance in a Sentence

1. Alon Gorodetsky:

   We've developed stickers for use as a thin, flexible layer of camo with the potential to take on a pattern that will better match the soldiers' infrared reflectance to their background and hide them from active infrared visualization.

2. Philip Goode:

   When we analyzed the last three years of data, it looked different, the reflectance had gone down and had gone down noticeably. So we thought we had done something wrong. So we redid it several times and it turns out it was correct.

3. Philip Goode:

4. Raymond Soneira:

   One challenging issue has always been switching from a rigid and hard cover glass protecting the current smartphones to a flexible and durable plastic cover protecting the flexible display, it needs to have superior optical properties and low reflectance like glass, and then also survive 50,000 or more opening and closing cycles.

5. Jay Neitz:

   Our visual system is supposed to throw away information about the illuminant and extract information about the actual reflectance, but I’ve studied individual differences in color vision for 30 years, and this is one of the biggest individual differences I’ve ever seen.
