  • question_answer
    The maximum spectral emissive power for a black body at temperature 5000K is obtained at\[{{\lambda }_{m}}=6000\overset{o}{\mathop{A}}\,.\] If the temperature is increased by 10% then decrease in \[{{\lambda }_{m}}\] will be (approximately)

    A) 3.5%

    B) 7.5%   

    C) 10%

    D) 5%

    Correct Answer: C

    Solution :

    [c] \[\frac{d\lambda }{\lambda }\times 100=-\left( \frac{dT}{T}\times 100 \right)=-10%\]
