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

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

$\therefore T=\frac{b}{{\lambda }_m}=\frac{2.93\times {10}^{-3}}{2.93\times {10}^{-10}}={10}^{7}K$
