The first three spectral lines of H-atom in the Balmer series are given `lamda _(1), lamda _(2), lamda _(3)` considering the
Bohr atomic model, the wave lengths of first and third spectral line `((lamda_(1))/( lamda _(3)))` are related by a factor of approximately` 'x' xx10^(-1)`
The value of x, to the nearest integer, is`"__________"`
