Consider Bohr's theory for hydrogen atom. The magnitude of angular momentum, orbit radius and frequency of the electron in `n^(th)` energy state in a hydrogen atom are l, r &f respectively. Find out the value of `x`. If (frl) is directly proportional to `n^(x)`.

Explanation

All possible transition are shown in the figures above . It can be seen, to get all possible transitions we need at least six atoms `(a,b,c,d,e,f,)`
