As compared to a person with white skin,a person with black skin will experience:

If $e_\lambda$ and $a_\lambda$ are the emissive power and absorptive power of a body respectively,and $E_\lambda$ is the emissive power of a perfectly black body,what is the relation according to Kirchhoff's law?

$A$ body has a black spot on it. When the body is heated and taken into a dark room,the black spot glows more brightly. This can be explained by which of the following?

When $170 \text{ J}$ of energy is incident on a surface of a body, $17 \text{ J}$ of energy is reflected by it. If the coefficient of absorption is $0.7$, then the amount of energy transmitted will be (in $\text{ J}$)

The surface of a thermos flask is kept shiny because:

The spectrum of black body radiation is a ...... .
