S.I. unit of emissive power is

If coefficient of absorption of a body is $0.74$ and coefficient of reflection is $0.22$, then a value of coefficient of transmission is 

When $150 \,\mathrm{J}$ of energy is incident on surface of a body, $15\,\rm{J}$ of energy is reflected by it. If the coefficient of absorption is $0.6,$ then the amount of energy transmitted will be 

Consider the following types of surfaces $A$ surface that is

I. Coated with lamp black

II. Polished

III. Painted white.

The correct sequence of the decreasing order of the emissive powers of the given surfaces will be

Coefficient of emission or emissivity$\left(e\right)$ is defined as

Coefficient of emission of a surface does NOT depend upon
