''A body with larger reflectivity is a poor emitter''. Why?

Text Solution

AI Generated Solution

To understand why a body with larger reflectivity is a poor emitter, we can break down the concepts involved in thermal radiation, reflectivity, and emissivity. ### Step-by-Step Solution: 1. **Definition of Reflectivity and Emissivity**: - Reflectivity (R) is the fraction of incident radiation that is reflected by a surface. - Emissivity (ε) is the measure of a material's ability to emit thermal radiation compared to that of a perfect black body. It is defined as the ratio of the radiation emitted by the body to the radiation emitted by a black body at the same temperature. ...
