For sodium light, the two yellow lines occur at \\lambda_{1} and \\lambda_{2} wavelengths. If the mean of these two is 6000 \Å and |\\lambda_{2}-\\lambda_{1}|=6 \Å, then the approximate energy difference between the two levels corresponding to \\lambda_{1} and \\lambda_{2} is

Correct Answer is : 2×10−3eV
