reflectance

Definitions

General Science

• noun the ratio of the energy of a wave reflected by a surface to the total wave striking the surface.

Cars & Driving

• noun the ratio of reflected luminous flux to that reflected from an ideal, perfectly reflecting surface when similarly illuminated

Computing

• noun the difference between the amount of light or signal incident and the amount that is reflected back from a surface.

Construction

• The ratio of light reflected from a surface to the light incident on the surface. Reflectances are often used for lighting calculations. The reflectance of a dark carpet is around 20%, and a clean white wall is roughly 50% to 60%.

Electronics

• The ratio of the amplitude of a wave reflected from a surface to the amplitude of the same wave incident upon the surface.
• The ratio of the current delivered to a load whose impedance is not matched to the source, to the current that would be delivered to the same load if its impedance were fully matched.
