JEE Main & Advanced Physics Transmission of Heat Question Bank Radiation Wein's law

  • question_answer
    A black body emits radiations of maximum intensity at a wavelength of \[5000{AA}\], when the temperature of the body is \[{{1227}^{o}}C\]. If the temperature of the body is increased by \[{{1000}^{o}}C\], the maximum intensity of emitted radiation would be observed at                                                               [MP PET 1992]

    A) \[2754.8{AA}\]                  

    B) \[3000{AA}\]

    C) \[3500{AA}\]                      

    D) \[4000{AA}\]

    Correct Answer: B

    Solution :

    \[{{\lambda }_{{{m}_{2}}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\times {{\lambda }_{{{m}_{1}}}}=\frac{1500}{2500}\times 5000=3000{AA}\]
