A black body is at a temperature of `2800K` The energy of radiation emitted by this object with wavelength between `499nm` and 500 nm is `U_(1)` between 999nm and 1000nm is `U_(2)` and between 1499 nm and 1500 nm is `U_(3)` The Wien's constant `b =2.80 xx 10^(6)` nm `K` Then .

Options

A. `U_(1)=0`
B. `U_(3)=0`
C. `U_(1)gtU_(2)`
D. `U_(2)gtU_(1)`

Answer

D

Explanation

For any temperature the energy is maximum in the middle range of wavelength So the energy is maximum for wavelength `1000nm` .
