Two black bodies A and B emit radiations with peak intensities at wavelengths 4000 A and 8000 A respectively. Compare the total energy emitted per unit area per second by the two bodies.

Two black bodies A and B emit radiations with peak intensities at wave

1.	Two black bodies A and B emit radiations with peak intensities at wavelengths 4000 A and 8000 A respectively. Compare the total energy emitted per unit area per second by the two bodies.
Answer» Solution :`(E_(1)//E_(2))=(T_(1)//T_(2))^(4)=(lamda_(M2)//lamda_(m1))^(4)=(8000//4000)^(4)=16:1`
