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 U1, between 999nm and 1000nm is U2 and between 1499 nm and 1500 nm is U3. Take weins constant 2.88 * 10^6 U1=0 U2>U1 U1>U2 U3=0

U1=0

U2>U1

U1>U2

U3=0

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 (b)
