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 \[{{U}_{2}}\] and between \[1499\ nm\] and \[1500\ nm\] is \[{{U}_{3}}\]. The Wein's constant\[b=2.88\times {{10}^{6}}\ nm\,K\]. Then [IIT 1998]

A.            \[{{U}_{1}}=0\]                   
B.            \[{{U}_{3}}=0\]
C.            \[{{U}_{1}}>{{U}_{2}}\]   
D.            \[{{U}_{2}}>{{U}_{1}}\]
