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.
