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