Question

One blackbody at temperature T is surrounded by another blackbody at temperate T₁ (T₁ < T). At T, the radiation emitted by inner blackbody per unit area per second is proportional to ____________.

पर्याय

• difference of temperature of two blackbodies

• fourth power of difference of temperature of two black - bodies

• difference of fourth powers of temperature of two bodies

• sum of fourth powers of temperature of the bodies

Answer 1

One blackbody at temperature T is surrounded by another blackbody at temperate T₁ (T₁ < T). At T, the radiation emitted by inner blackbody per unit area per second is proportional to difference of fourth powers of temperature of two bodies.
