Answer & Solution

Correct Answer

(A) \(27\)

Step-by-step Solution

Detailed explanation

\(\frac{1}{\lambda}= R \left[\frac{1}{ n _1{ }^2}-\frac{1}{ n _2{ }^2}\right]\) for \(H\)-atom For balmer series, \(n _1=2\) \(\frac{1}{\lambda}= R \left[\frac{1}{4}-\frac{1}{ n _2^2}\right]\) For \(H _{ i }, n _2=3\) \(H _\beta, n _2=4\)…
