Minimum wave length of the line in the Lyman series of hydrogen spectrum is x. What would be the wave length of first line in Balmer series :-

A

9x/5

B

36x/5

C

5x/9

D

5x/36

Text Solution

Verified by Experts

The correct Answer is:
B
`(1)/(lamda _(min))=R((1)/(1^(2))-0)`
`(1)/(lamda_(1))=R((1)/(2^(2))=-(1)/(3^(2)))`
`(lamda_(1))/(x)=(1xx36)/(1xx5)`
`lamda_(1) =(36)/(5) x`
