Molecular Vibration: a Certain Diatomic Molecule Emits a Photon of Energy

question 11

Multiple Choice

Molecular vibration: 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, ħ = 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

Definitions:

Conglomerate

A coarse-grained sedimentary rock composed of rounded clasts (rock fragments) cemented by finer-grained materials.

Igneous Rocks

Rocks formed through the cooling and solidification of magma or lava, categorized into intrusive and extrusive types.

Metamorphic Rock

Rock that has been transformed from an original form (sedimentary or igneous) into a new form through heat, pressure, and chemical processes, without melting.

River Terrace

A flat, bench-like structure alongside a river, formed by the river cutting deeply into the land then retreating, leaving a raised platform.
