A black body is at a temperature of \(5760~\text{K}.\) The energy of radiation emitted by the body at wavelength \(250~\text{nm}\) is \(U_1,\) at wavelength \(500~\text{nm}\) is \(U_2\) and that at \(1000~\text{nm}\) is \(U_3.\) Wien’s constant, \(b=2.88 \times 10^6~ \text{nm-K}.\) Which of the following is correct?
1. \({U}_3 =0 \)
2. \({U}_1 >{U}_2 \)
3. \({U}_2 >{U}_1 \)
4. \({U}_1 =0\)
1. \({U}_3 =0 \)
2. \({U}_1 >{U}_2 \)
3. \({U}_2 >{U}_1 \)
4. \({U}_1 =0\)
