Maximum Number of Transitions from an Excited State
Correct answer: B. 4
- A. 6
- B. 4
- C. 10
- D. 3
Explanation
The maximum number of transitions from \(n = 5\) occurs when the atom transitions to all lower energy states (\(n' = 4, 3, 2, 1\)), resulting in \(5 - 1 = 4\) transitions.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
