Answer» 4 For n=1 to `n=oo`, transition is ionisation ENERGY of hydrogen, `13.6 =E_(0) (1/1^(2)-1/oo^(2)) or E_(0)=13.6eV` `E_(n)=-(13.6)/(n^(2))eV` `E_(n)=-(13.6)/(n^(2)eV` `E=hv=(hc)/(lambda)=2.04 XX 10^(-18)J` Let the ELECTRON jump from n=1 n=m after absorbing photon  `triangleE=E_(m)-E_(1)=13.6 (1/1^(2)-1/m^(2))eV` then m=4 so there ar 6 possible lines EVOLVED. |
