For an enclosure maintained at 1000 ~K , the maximum radiation occurs at wavelength _ m . If the temperature is raised to 2000 ~K , the peak will shift to

Options

  1. A5 2 _m
  2. B1 2 _m
  3. C7 2 _m
  4. D3 2 _m .

Correct answer

B. 1 2 _m

Step-by-step solution

We know from Wien's displacement law, aligned & _m T= constant & _m T_l= _m^ T₂ & _m^ = _m T₁ T₂ = _m 1000 2000 = _m 2 aligned
