 (rĭ-flĕk′təns)
n.
The ratio of the total amount of radiation, as of light, reflected by a surface to the total amount of radiation incident on the surface.

reflectance

(rɪˈflɛktəns) or

reflection factor

n
(Units) a measure of the ability of a surface to reflect light or other electromagnetic radiation, equal to the ratio of the reflected flux to the incident flux. Symbol: ρ Compare transmittance, absorptance

re•flect•ance

(rɪˈflɛk təns)
