A medical researcher studies the emission spectrum of a hydrogen atom. What type of transition occurs when an electron moves from the first excited state to the ground state?
Q1. A medical researcher studies the emission spectrum of a hydrogen atom. What type of transition occurs when an electron moves from the first excited state to the ground state?
Answer: Quantum leap
Explanation: Correct: Quantum leap describes the transition from first excited state to ground state. Tempting option C fails because it's a real concept, but doesn't apply to atomic transitions.
