To solve the problem of an excited `He^(+)` ion emitting a photon of wavelength `lambda` while returning to the ground state from the `n^(th)` orbit, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Initial and Final States**: - The excited helium ion is transitioning from the `n^(th)` orbit to the ground state (which corresponds to `n = 1`). 2. **Use the Rydberg Formula**: ...
