no of line in line spectrum is equal to jumps of electron from one shell to another. Am i correct.
IN my book it is written that if a electron in hydrogen jumps from n1 to n2 then number of spectral lines is given by formula {(n1-n2)(n1-n2+1}/2. so consider a electron jump from 4th shell to 2nd shell then number of kinds of jump can be (1) 4th to 3rd,(2) 4th to 2nd So there are only two jumps. but if we apply formula then it will come out to be 3. So where i or formula is wrong.
thanks for any kind of help.
