A black body at temperature T emits radiation with peak wavelength $\lambda_\rho$ and power P.

What is the temperature of the black body and the power emitted for a peak wavelength of $\frac{\lambda_\rho}{2}$?

	Temperature of the black body	Power emitted by the black body
A.	$\frac{T}{2}$	$\frac{P}{16}$
B.	$\frac{T}{2}$	$\frac{P}{4}$
C.	$2 T$	$4 P$
D.	$2 T$	$16 P$
