A perfectly black body emits a radiation at temperature ' T ₁ ' K . If it is to radiate at 16 times this power, its temperature ' T ₂ ' K should be

Options

  1. A8 ~T ₁
  2. B4 ~T ₁
  3. C2 ~T ₁
  4. D16 ~T ₁

Correct answer

C. 2 ~T ₁

Step-by-step solution

aligned & P ₂ P ₁ = ( T ₂ ~T ₁ )^4 & 16= ( T ₂ ~T ₁ )^4 & T ₂ ~T ₁ =2 aligned
