Question

state and prove stefen's law of black body radiation​

Answer 1

Answer:

state and prove stefen's law of black body radiation Are.

Stefan's Law states that the radiated power density (W/m2) of a black body is proportional to its absolute temperature T raised to the fourth power. E = e σ T4. The emissivity e is a correction for an approximate black body radiator, where e = 1 – R, is the fraction of the light reflected (R) by the black body.

Answer 2

✪ Stefen Law :

According to stefen law total energy emiitted by black body per unit time , per unit second , per unit area , is directly proportional to fourth power of absolute temperature

✪ Expression :

• e ∝ T ⁴
