Question

= 7 2 points Return Next Which is the correct definition that describes the term "emissivity, &," Emissivity is a form of waste energy given off by heat radiation. Is the ratio of the area of the large object to that of the small object between which the radiant heat transfer is occurring Emissivity is the ratio between the energy radiated from real surface to that of the perfect emitter, i.e. a blackbody, at the same temperature and wavelength. It ranges between a value of 0 and 1. Emissivity is related to how an object orbits another object.
