Questions: What happens to electrons on the surface of the metal sheet?

Solution Steps

When white light (which contains photons of various energies) shines on a metal sheet, it can cause electrons to be ejected from the surface of the metal. This phenomenon is known as the photoelectric effect.

• The kinetic energy of the electrons decreases: This is not correct because the kinetic energy of the electrons would increase if they are ejected.
• Some electrons are ejected from the sheet: This is correct as it describes the photoelectric effect.
• Some electrons are pushed farther into the sheet: This is not correct because the energy from the light causes electrons to be ejected, not pushed further in.
• The charge on the electrons increases: This is not correct because the charge of an electron is a fundamental property and does not change.
