In a dark room with ambient temperature $\mathrm{T}_0$, a black body is kept at a temperature T . Keeping the temperature of the black body constant (at T), sunrays are allowed to fall on the black body through a hole in the roof of the dark room. Assuming that there is no change in the ambient temperature of the room, which of the following statement(s) is/are correct?
Select ALL correct options:
A
The quantity of radiation absorbed by the black body in unit time will increase.
B
Since emissivity $=$ absorptivity, hence the quantity of radiation emitted by black body in unit time will increase.
C
Black body radiates more energy in unit time in the visible spectrum.
D
The reflected energy in unit time by the black body remains same.
