The shortest wavelength in hydrogen spectrum of Lyman series when `R_(H)=109678 cm^(-1)` is :-

A

1002.7 Å

B

1215.67 Å

C

1127.30 Å

D

911.7 Å

Text Solution

Verified by Experts

The correct Answer is:
D
The shortest wavelength in hydrogen spectrum of Lyman series is given by formula :
`1/lamda=R_(H)/n^(2)=R_(H)/1^(2)=109678/1rArrlamda=9.1170xx10^(-6)cm`.
