Question

Which observation cannot be explained by the wave picture of continuous energy absorption?

Options

• Greater amplitudes of the electric and magnetic fields

• The immediate emission of electrons from the metal surface

• The natural and satisfactory explanation of interference

• A continuous distribution of energy over the region of space

Answer 1

Continuous absorption suggests that an electron may require hours or more to gain enough energy to escape. The wave picture therefore cannot explain the immediate emission of electrons from the metal surface.
