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.            \[5.86\times {{10}^{7}}K\]
