The frequency ' v_m ' corresponding to which the energy emitted by a black body is maximum may vary with the temperature ' T ' of the body as shown by the curves ' A ', ' B ', ' C ' and ' D ' in the figure. Which one of these represents the correct variation?

Options

  1. Astraight line D
  2. Bcurve C
  3. Cstraight line B
  4. Dcurve A

Correct answer

C. straight line B

Step-by-step solution

According to Wien's displacement law, aligned & _m 1 T or c _m 1 T & _m T aligned Hence, curve B represents the correct variation.
