Transmission Of Heat Question 268

Question: 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]

Options:

A) $ {{10}^{-7}}K $

B) $ 10^{7}K $

C) $ {{10}^{-13}}K $

D) $ 5.86\times 10^{7}K $

Show Answer

Answer:

Correct Answer: B

Solution:

$ \

Therefore \ T=\frac{b}{{\lambda _{m}}}=\frac{2.93\times {{10}^{-3}}}{2.93\times {{10}^{-10}}}=10^{7}\ K $
