A black Body is at a temperature of 2880K.The energy of radiation emiited by this object with wavelength between 499nm and 500nm is U1, between 999nm and 1000nm is U2 and between 1499nm and 1500nm is U3.The Wien constant,b is 2.88*10^6 nm-K.Then(a)U1= 0(b)U3= 0(c)U1>U2(d)U2>U1

A black body at a given temperature emits different amounts of energy at different wavelengths. Wien' law states that the maximum energy is emitted at wavelength lambda =b/T= 1000k,
Therefore, answer is (d)
