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

  • question_answer
    The wavelength of maximum energy released during an atomic explosion was \[2.93\times {{10}^{-10}}m\]. Given that Wein's constant is \[2.93\times {{10}^{-3}}m-K\], the maximum temperature attained must be of the order of [Haryana CEE 1996; MH CET 2002; Pb. PET 2000]

    A)            \[{{10}^{-7}}K\]                   

    B)            \[{{10}^{7}}K\]

    C)            \[{{10}^{-13}}K\]                

    D)            \[5.86\times {{10}^{7}}K\]

    Correct Answer: B

    Solution :

               \[\therefore \ T=\frac{b}{{{\lambda }_{m}}}=\frac{2.93\times {{10}^{-3}}}{2.93\times {{10}^{-10}}}={{10}^{7}}\ K\]
