Definitions
in optics
The fraction of incident electromagnetic radiation reflected by a surface.
Synonyms
reflection coefficient, reflectivity.
Which Synonym Should You Choose?
| Word | Description / Examples |
|---|---|
| reflectance |
Used primarily in physics and optics to describe the proportion of light or other radiation striking a surface that is reflected. It is often quantified for materials to understand their reflective properties.
|
Examples of usage
- The reflectance of the mirror was very high.
- The reflectance of the glass increased with the angle of incidence.
in remote sensing
The ratio of the radiant flux reflected by an object to that incident on it.

| Word | Description / Examples |
|---|---|
| reflectance |
Used primarily in physics and engineering to describe the proportion of light or other radiation striking a surface and reflecting off it.
|
| albedo |
Commonly used in astronomy and climatology to describe the proportion of the incident light or radiation that is reflected by a surface, often of celestial bodies or Earth's surfaces.
|
| reflectivity |
Frequently used in optics and materials science to describe the ability of a surface or material to reflect light or other kinds of radiation.

Examples of usage
- The satellite measured the reflectance of the Earth's surface.
- The vegetation had a high reflectance in the near-infrared spectrum.
Interesting Facts
Science
- Different materials reflect light in unique ways; for example, mirrors reflect nearly all light, while dark surfaces absorb most of it.
- Reflectance is important in studying climate change because it affects how much heat the Earth absorbs and how it maintains temperature.
- Photovoltaic cells (solar panels) rely on reflectance principles to capture sunlight efficiently and convert it into electricity.
Technology
- In digital imaging, high reflectance improves the quality of images captured by cameras and sensors.
- Reflectance is key in designing surfaces in automotive and architectural fields to enhance energy efficiency and reduce cooling costs.
Psychology
- Light reflectance can influence mood; bright, reflective spaces are often seen as uplifting and energizing.
- Color psychology suggests that lighter colors with high reflectance can contribute to a sense of openness and creativity.
Art
- Artists use reflectance in their work; shiny paint or materials can create dynamic visual experiences in sculpture and installations.
- The concept of reflectance influences photography techniques, as photographers manipulate light to capture the best images.
Environment
- Reflectance plays a vital role in understanding ecosystems; surfaces like ice and water have high reflectance, impacting local climates.
- Urban planning considers reflectance to design parks and buildings that maximize light reflection, promoting cooler city environments.
