An electron in a hydrogen atoms makes a transition form `n_1` to `n_2` where `n_1 and n_2` are two principal quantum numbers of two states. If time period of electron in state `n_1` is 8 times the time period in state `n_2`, find the ratio `(n_2//n_1)`, assuming Bohr model to be true.A. `8:1`B. `4:1`C. `2:1`D. `1:2`

Answer» Correct Answer - C
Time period of revolution of electron in the nth orbit
is `T` a `jn^(3) `
