# The ratio of walength of photon corresponding to the “x” line of Lyman series in H-atom and “y” line of Baler series in He+ is 1:1 1:2 1:4 3:16

the wavelength of any line of lyman series is given by
=

and that of balmer series is

[\lambda] is the wavelength.
Bis a constant with the value of 3.6450682×10-7m or 364.50682 nm.
mis equal to 2
nis an integer such thatn>m.

fror helium just put the atomic number square

here x line and the y line is not clearly mentioned.
