The ratio of the longest and shortest wavelengths of the Lyman series is approximately
Correct answer: A. 4/3
- A. 4/3
- B. 9/5
- C. 9/4
- D. 16/7
Explanation
A is the right option Here's why:we used the Rydberg formula to find the approximate wavelengths for the longest and shortest transitions in the Lyman series. By taking the ratio of these estimated values, we arrived at 3/4, which is the reciprocal of the desired ratio. Since we're dealing with ratios and want the longest over the shortest, we need to flip the result, leading to 4/3 as the most accurate answer.

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.
