HEAT: Multi C...

Question

HEAT: Multi Correct: Two spheres A and B having radii rA and rB where rB =2rA emit radiations with peak intensities at wave lengths 400 nm and 800 nm respectively. If their temperature are TA and TB respectively in Kelvin scale, their emissive powers are EA and EB and energies emitted per second are PA and PB then A. TA / TB = 2 B. PA / PB = 4 C. EA / EB = 8 D. EA / EB = 4
