Question

If $v_{1}$ is the frequency of series limit of Lyman series, $v_{2}$ is frequency of first line of Lyman series and $v_{3}$ is frequency of series limit of Balmer series then :-

• A. $v_{1}+v_{2}=v_{3}$
• B. $v_{2}-v_{1}=v_{3}$
• C. $v_{1}-v_{2}=v_{3}$
• D. $v_{3}=\frac{1}{2}\left(v_{1} + v_{2}\right)$

Answer 1

Answer: (C)

$E_{1}-E_{2}=E_{3}$
$hv_{1}-hv_{2}=hv_{3}$
$v_{1}-v_{2}=v_{3}$
