For reflections at flat unstructured surfaces, instead of reflectance one may also use the term reflectivity. However, the reflectance is a more general term and can be specified in a wider range of situations:

For homogeneous and semi-infinite (see halfspace) materials, reflectivity is the same as reflectance. Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the reflection coefficient can be expressed as a complex number as determined by the Fresnel equations for a single layer, whereas the reflectance i…
