Out of the following transitions in hydrogen atom, identify the transition which emits photons of highest frequency.
- A \(\mathrm{n}=1\) to \(\mathrm{n}=2\)
- B \(\mathrm{n}=2\) to \(\mathrm{n}=1\)
- C \(\mathrm{n}=2\) to \(\mathrm{n}=6\)
- D \(\mathrm{n}=6\) to \(\mathrm{n}=2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{n}=2\) to \(\mathrm{n}=1\)
Step-by-step Solution
Detailed explanation
To emit photons, \( \mathrm{n_{initial}} > \mathrm{n_{final}} \). Highest frequency corresponds to largest energy difference \( \Delta E \propto (\frac{1}{\mathrm{n_{final}}^2} - \frac{1}{\mathrm{n_{initial}}^2}) \).
