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.


(rɪˈflɛktəns) or

reflection factor

(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


(rɪˈflɛk təns)

the ratio of the intensity of reflected radiation to that of the radiation incident on a surface.
