    D)         6500 K

    Correct Answer: C

    Solution :

          According to the Wiens displacement law, \[{{({{\lambda }_{m}})}_{1}}{{T}_{1}}={{({{\lambda }_{m}})}_{2}}{{T}_{2}}\] \[\Rightarrow \]               \[500\times 6000=400\times {{T}_{2}}\]                 \[{{T}_{2}}=\frac{500\times 6000}{400}=7500K.\]
