    Shown below are the black body radiation curves at temperatures T1 and T2 (T2>T1). Which of the following plots is correct                                                        [AIIMS 2003]

    A) Intensity                

    B)  

    C)                 

    D)  

    Correct Answer: A

    Solution :

                       According to Wein?s displacement law                    \[{{\lambda }_{m}}\propto \frac{1}{T}\] \[\Rightarrow \,{{\lambda }_{{{m}_{2}}}}<{{\lambda }_{{{m}_{1}}}}\]  \[(\because \,\,\,\,{{T}_{1}}\,\,<{{T}_{2}})\] Therefore I?l graph for T2 have lesser wavelength (lm) and so curve for T2 will shift towards left side.
