reflectance
This term is a technical specification used primarily in physics, optics, and materials science. It describes a precise ratio or percentage, distinguishing it from the general act of reflecting light. While "reflection" refers to the phenomenon or the image produced, "reflectance" refers specifically to the quantitative measurement of that phenomenon.
As a technical term denoting a physical property, it is treated as an uncountable noun. It describes a characteristic of a surface rather than a discrete object, meaning it does not typically take a plural form in scientific discourse.
