For an ideal black body
(A) absorptivity = 1
(B) reflectivity = 1
(C) emissivity = 0
which is true???????
Answer Posted / jayesh
ideal black bodu absorbs whole amt of radiation inserted on it
thus absorbance = 1
as the body absorbs all thing thus reflects none
so reflectivity = 0
now good absorber is always good emitter for the case of black body
emissivity = 1
following this sequence answer is (A)
