Question

A black body emits radiation at the rate P when its temperature is T. At this temperature the wavelength at which the radiation has maximum intensity is ${\lambda }_0$.

• A. $T^{\prime }=2T$
• B. $T^{\prime }=T/2$
• C. $P^{\prime }=2P$
• D. $P^{\prime }=P/16$

Answer 1

Answer: (A)

$T^{\prime }=2T$

Hence, option $\left(A\right)$ is correct answer.
