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

  • question_answer
    Two stars emit maximum radiation at wavelength 3600\[{AA}\] and 4800\[{AA}\] respectively. The ratio of their temperatures is [MP PMT 1991]

    A) 1 : 2                                          

    B) 3 : 4

    C) 4 : 3                                          

    D) 2 : 1

    Correct Answer: C

    Solution :

    \[\frac{{{T}_{1}}}{{{T}_{2}}}=\frac{{{\lambda }_{{{m}_{2}}}}}{{{\lambda }_{{{m}_{1}}}}}=\frac{4800}{3600}\Rightarrow \frac{48}{36}=\frac{4}{3}\]
