An atomic level has a lifetime,τ,of 
)What is the linewidth, 
,of this level?

Quizplus · Accepted Answer

According to the uncertainty principle, the linewidth (∆ν) is related to the lifetime (τ) by the equation ∆ν = 1/(2πτ). Substituting the given lifetime value of 11ea7ff9_2c63_49a8_a768_1d990b6509b5_TB2295_11, we get ∆ν = 1/(2π × 11ea7ff9_2c63_49a8_a768_1d990b6509b5_TB2295_11) which is equal to 11ea7ff9_2c63_70bb_a768_45d8a5874bd1_TB2295_11. Therefore, the correct answer is B.
