In a sample of h atom electrons make transition from 5 th exited state to ground state producing all possible type of photon then no of line
Hello,
The formula to find the number of lines for this problem -> n(n-1)/2, when one ground state and excited state are given.
and when both are of excited state then the formula is [(n1-n2)(n1-n2+1)]/2. Hope you will find the desired answer.
