A black body is at a temperature of 2880 K. The energy of radiation emitted by this object with wavelength between 499 nm and 500 nm is \[{{U}_{1}}\] between 999 nm and 1000 nm is \[{{\operatorname{U}}_{2}}\] and between 1499 nm and 1500 nm is \[{{\operatorname{U}}_{3}}\] Wien's constant \[\operatorname{b}=2.88\times {{10}^{6}}nm-K\]. Then

A) \[{{\operatorname{U}}_{1}}=0\]

B) \[{{\operatorname{U}}_{2}}=0\]

C) \[{{\operatorname{U}}_{1}}={{U}_{2}}\]

D) \[{{\operatorname{U}}_{2}}>{{U}_{1}}\]
