Question

the wave length of first line of Lyman series is x A° what is the wave length of first line of balmer series in H spectrum​

Answer 1

Answer:

given that

For first line in Lyman series

For first line in Lyman series

1/λl=R( 1/1^2-1/2^2)=3R/4

first line of balmer seties

1/λb=R(1/4-1/9)=5R/36

λl/λb=27,/5

λb=27/5x
