Multiple Choice
Which phenomena can be explained by the wave model of light, and which by the particle model, according to the chart shown?
Reflection, refraction, and polarization by wave model; photoelectric effect by particle model.
Interference and diffraction by particle model; reflection and refraction by wave model.
Photoelectric effect and polarization by wave model; diffraction by particle model.
All phenomena by both models equally.

Multiple Choice
What is the role of photons in the context of atomic energy levels?
Photons are emitted or absorbed when electrons transition between energy levels.
Photons determine the mass of an electron.
Photons are responsible for the nuclear forces within an atom.
Photons have no role in atomic energy levels.

Multiple Choice
What happens to most infrared photons when they encounter a carbon monoxide molecule?
They pass by the molecule, but occasionally one is absorbed and causes vibration.
They are all absorbed by the molecule.
They are reflected by the molecule.
They cause the molecule to break apart.
