Question 1

For hydrogen, what is the wavelength of the photon emitted when an electron drops from a 3d orbital to a 2p orbital in a hydrogen atom? The Rydberg constant is 1.097 × 10-2 nm-1.
◦ 364.6 nm
◦ 656.3 nm
◦ 486.2 nm
◦ 2.057 × 10-3 nm

Question 2

Molecular vibrational energy transitions are observed in the infrared, molecular rotational transitions in the microwave, and electronic transitions in the ultraviolet-visible range. Which transitions require the most energy and which the least energy?
◦ Electronic transitions require the least energy and vibrational transitions the most.
◦ Vibrational transitions require the least energy and electronic transitions the most.
◦ Vibrational transitions require the least energy and rotational transitions the most.
◦ Rotational transitions require the least energy and electronic transitions the most.
