Question

Ratio of maximum frequency of Lyman and balmer series

Answer 1

For maximum frequency.. Take last line.. i. e, N2 = infinite for both lyman and balmer.. And n1 for lyman is 1.. N1 for balmer is 2..then solve.. U will get the answer..

Answer 2

maximum frequency of Lyman series

(1/wavelength)=91.2

maximum frequency of balmar series

(1/wavelength)=364.5

ratio=frequency of lyman/freq of balmar

ratio=0.25
