Q. Which of the following graphs correctly represents the relation between $ln\left(E\right)$ and $ln\left(T\right)$ , where $E$ is the amount of radiation emitted per unit time from a unit area of the body and $T$ is the absolute temperature?

Solution:

We know,
$E=\epsilon \sigma T^{4}$
$\Rightarrow ln E=ln⁡\epsilon \sigma +4ln⁡T$
$εσ < 1$ , hence, $ln\epsilon \sigma $ is negative.
