Definition of reflectivity in English: reflectivitynoun riːflɛkˈtɪvɪti Physics The property of reflecting light or radiation, especially reflectance as measured independently of the thickness of a material. Example sentencesExamples - These variations between the two bands depend on emissivity and reflectivity of the materials that make up the target and/or background.
- This application involves measuring the reflectivity of monochromatic x-rays as a function of the incident angle.
- Aluminum has a light reflectivity of over 80 percent, which has led to its wide use in lighting fixtures.
- When polished, silver has the highest-known reflectivity of visible light.
- Light reflectivity is another key performance area.
