    If for a blackbody the graph of change is emissive power at different temperatures \[{{T}_{1}},{{T}_{2}}\] and \[T{{  }_{3}}\] with wavelength is according to the figure then.            

    A)  \[{{T}_{1}}={{T}_{2}}={{T}_{3}}\]                

    B)  \[{{T}_{3}}>{{T}_{2}}>{{T}_{1}}\]

    C)  \[{{T}_{1}}>{{T}_{2}}>{{T}_{3}}\]                

    D)  \[{{T}_{3}}>{{T}_{1}}>{{T}_{3}}\]

    Correct Answer: B

    Solution :

    By Wein's law wave length for which emissive power is maximum is inversly proportional to temperature.
