Etymology
The word 'reflectance' originated in the field of optics, where it is used to describe the proportion of light that is reflected by a surface. Over time, the term has also been adopted in remote sensing to refer to the ratio of reflected radiant flux. The concept of reflectance plays a crucial role in various scientific fields, including physics, astronomy, and environmental studies.
