Question #13246

number of spectral lines when electron jumps from n=4 to ground state if two atoms are present in the sample

Expert's answer

the formula for no. of spectral line is (n2-n1)(n2-n1+1)/2

where& n1=1, n2=4

therefore no of spectral lines = 6

where& n1=1, n2=4

therefore no of spectral lines = 6
