Black body radiation – Wien's displacement law

2016 1 question

1. 1 Thermal Properties of Matter
   A black body is at a temperature of 5760 K. The energy of radiation emitted by the body at wavelength 250 nm is $U_1$, at wavelength 500 nm is $U_2$ and that at 1000 nm is $U_3$. Wien's constant, $b = 2.88 \times 10^{6}$ nmK. Which of the following is correct?
   A $U_3 = 0$ B $U_1 > U_2$ C $U_2 > U_1$ D $U_1 = 0$
