Question

How does each photon interact with electrons in the photoelectric effect?

Options

• Each photon interacts with one electric or magnetic field.

• Each photon interacts with every electron in the metal.

• Each photon interacts with one electron.

• Each photon interacts only with the work function.

Answer 1

Each photon interacts with one electron. Whether that electron is emitted depends on the photon energy relative to the work function.
