Calculate frequency, energy and wavelength of the radiation corresponding to the speciral line of the lowest frequency in lyman series in the spectrum of a hydrogen atom .Also calculate the energy for the coresponding line in the spectrum of `Li^(2+).(R_(H) = 109677 cm^(-1), c = 3 xx 10^(8) m s^(-1), Z = 3)`

Explanation

`lambda=1215 Å , v= 2. 469 xx 10^(15) Hc, E= 16 . 36 xx 10^(-19) J`,
`F+90Li^(2+) = 14. 7 xx 10^(-18) J,`
