The temperature of the black body increases from T to 2 T . The factor by which the rate of emission will increase, is?

Options

  1. A4
  2. B2
  3. C16
  4. D8

Correct answer

C. 16

Step-by-step solution

According to Stefan's law for radiated energy E T^4 Hence, E₁ E₂ = T₁^4 T₂^4 = ( T 2 T )^4= 1 16 E₂=16 E₁
