In hydrogen spectrum, if the shortest wavelength in Balmer series is \(\lambda\), the shortest wavelength in Brackett series is
- A \(\lambda\)
- B \(\lambda / 2\)
- C \(4 \lambda\)
- D \(9 \lambda\)
Answer & Solution
Correct Answer
(C) \(4 \lambda\)
Step-by-step Solution
Detailed explanation
For Balmer series, \(\frac{1}{\lambda_{\text {Balmer }}}=R\left(\frac{1}{2^2}-\frac{1}{n^2}\right)\), where \(n=3,4,5 \ldots\) For shortest wavelength, \(n=\infty\)…

- Assertion (A): In a elastic collision of two billiard balls, both kinetic energy and linear momentum remain conserved. Reason (R): During the collision of the balls, as the collision is elastic there is no exchange of energy. Therefore, both energy and momentum are conserved.
