Two bodies A and B have emissivities 0.5 and 0.8 respec .At some tempt the two bodies have emissive powers at these tempt.

To find exact value of of emissive power you need to have temperature of the surface and surface area of body.
Since emissive power is directly propotional to emissivity
So Pa/Pb=0.5/0.8
