Question:
The wavelength of an electron for transition from a state \(n_1\) to \(n_2\) is \( \frac{9}{8R} \). Which of the following wavelengths is possible for a transition from \(n_2\) to \(n_1\)?
The wavelength of an electron for transition from a state \(n_1\) to \(n_2\) is \( \frac{9}{8R} \). Which of the following wavelengths is possible for a transition from \(n_2\) to \(n_1\)?
Show Hint
In atomic transitions, the wavelength of emitted or absorbed light is inversely related to the energy difference between the levels.

The Correct Option is C
Solution and Explanation
Step 1: Relation between Wavelength and Energy.
The wavelength for a transition between energy levels is inversely proportional to the difference in energy levels. Using the given information, the wavelength for the reverse transition would be directly related to the energy difference, resulting in \( 9R \).
Step 2: Conclusion.
The correct answer is (C), \( 9R \).
