If an electron in the hydrogen atom jumps from second to first orbit, the emitted radiation has a wavelength of?
Answer: 4/3RH
Explanation
The wavelength of the radiation emitted when an electron in a hydrogen atom jumps from a higher orbit (n = 2) to a lower orbit (n = 1) can be calculated using the Rydberg formula:
