Question

Which phenomena were explained in a natural and satisfactory way by the wave picture of light?

Options

• Radiant energy, kinetic energy, and work function

• Interference, diffraction, and polarisation

• Electric fields, magnetic fields, and free electrons

• Photoelectric emission, work function, and threshold frequency

Answer 1

Interference, diffraction, and polarisation were explained by the wave picture of light. Its success with these phenomena did not mean it could explain photoelectric emission.
