question 6

Multiple Choice

A certain diatomic molecule emits a photon of energy 1.20 eV when it makes a transition from the n = 1 vibrational state to the next lower vibrational state. What is the frequency of vibration of the molecule? (h = 6.626 × 10^-34 J ∙ s, = 1.055 × 10^-34 J ∙ s, 1 eV = 1.60 × 10^-19 J)

• A) 1.93 × 10¹⁴ Hz
• B) 2.90 × 10¹⁴ Hz
• C) 4.35 × 10¹⁴ Hz
• D) 1.82 × 10¹⁵ Hz
• E) 2.73 × 10¹⁵ Hz
