Reflectivity or reflectance
Did you know?
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 … See more The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the See more Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give See more The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.

WebAug 27, 2024 · Incident EM wave generates an inverse wave via the metal's free electrons that cancels out the incoming wave (1). That's why metals are so reflective. At some frequencies the free electrons are excited to a new band and that's why some colors don't reflect and metals have colored reflections (2). Aug 28, 2024 at 13:40.
