Question
A black body is at a temperature of 2880 K. The
energy of radiation emitted by this object with wave length between 250 nm to
255 nm is U1, between 500 nm to 505 nm is U2and between 1500 nm to 1505 nm is U3.
Then for this situation mark the correct statement

Solution
The correct option is C U1< U2
From black body radiation curve,the area of the shaded strips are U1,U2 and U3.
It is obvious that U1,U2 and U3 can't be zero and U2>U1.
U1< U2
From black body radiation curve,the area of the shaded strips are U1,U2 and U3.
It is obvious that U1,U2 and U3 can't be zero and U2>U1.
