Question

The energy distribution E with the wavelength left parenthesis lambda right parenthesis for the black body radiation at temperature T   K e l v i nis shown in the figure. As the temperature is increased the maxima will

  1. Shift towards left and become higher    
  2. Rise high but will not shift    
  3. Shift towards right and become higher    
  4. Shift towards left and the curve will become broader    

The correct answer is: Shift towards left and become higher


    According to Wein's displacement law lambda subscript m end subscript proportional to fraction numerator 1 over denominator T end fraction. Hence, if temperature increases lambda subscript m end subscript decreases i.e., peak of the E minus lambda curve shift towards left.
