Which of the following statement is correct in connection with hydrogen spectrum

Options

A. The longest wavelength in the Balmer series is longer than the longest wavelength in Lyman series
B. The shortest wavelength in the Balmer series is shorter then the shortest wavelength in the Lyman series
C. The longest wavelength in both Balmer and Lyman series are equal
D. The longest wavelength in Balmer series is shorter than the longest wavelength in the Lyman series.

Answer

A

Explanation

`Lambda` longest Rightarrow `E_(min)`
for Balmer lambda longest is for `n =2 rightarrow 3`
for Lyman lambda longest is for `n =1 rightarrow 2`
`Rightarrow lambda longest Balmer gt Lambda longest Lyman`
