The average lifetime for the `n = 3` excited state of a hydrogen-like atom is `4.8 xx 10^(-8) s` and that for the `n = 2 state is 12.8 xx 10^(-8) s`. The ratio of average number of revolution made in the `n = 3` sate before any transition can take place from these state is.

The average lifetime for the `n = 3` excited state of a hydrogen-like

1.	The average lifetime for the `n = 3` excited state of a hydrogen-like atom is `4.8 xx 10^(-8) s` and that for the `n = 2 state is 12.8 xx 10^(-8) s`. The ratio of average number of revolution made in the `n = 3` sate before any transition can take place from these state is.
Answer» Correct Answer - 9 Numbersof revolution before transition = `"frequency"` xx times Also, ` "frequency" prop (1)/(n^(3))` `"So required ratio" = ((1//2) 12.8 xx 10^(-8))/((1//3) 4.8 xx 10^(-8)) = 9`
