Step 1
An opaque body is a material that does not allow light or any other form of electromagnetic radiation to pass through it. This means that when thermal radiation is incident on an opaque body, it is either absorbed or reflected. It cannot be transmitted through the Show more…

Statement-1 : A body that is a good radiator is also a good absorber of radition at a given wavelength. Statement-2 : According to Kirchoff's law the absorptivity of a body is equal to its emissivity at a given wavelength.

Section E
A black body is an ideal system that. a) absorbs $100 \%$ of the light incident upon it, but cannot emit light of its own. b) radiates $100 \%$ of the power it generates, but cannot absorb radiation of its own c) either absorbs $100 \%$ of the light incident upon it, or radiates $100 \%$ of the power it generates. d) absorbs $50 \%$ of the light incident upon it, and emits $50 \%$ of the radiation it generates. e) blackens completely any body that comes in contact with it.
Statement-1 : If $a, r$ and $t$ are absorptive, rellective and transmitting powers of body then $a+r+t=1$ Statement-2: For $t \rightarrow 1$ the body will be diathermanous.
