The ratio of the energy absorbed by
the body to total energy falling on it is called ________ .
absorptive power
emissive power
emissivity
none of these
absorptive power
Absorptive power is a measure of heat
absorbed by an object.When heat is incident on the surface of an object, a part
of it absorbed and the remaining part is reflected. Usually the absorbed
radiation is converted to thermal energy increases the object’s temperature.
Absorptivity 
Hence, the correct option is (A).
