Question

which event causes the formation of the electric current produced by the photoelectric effect? a. the waves of light cause electrons to flow in different directions within an atom. b. electrons are particles, so they flow through the air from a light bulb to a metal surface. c. electrons flow in waves from one atom to another when light strikes them. d. electrons are knocked off the surface that the light strikes by particles of light.

Explanation:

The photoelectric effect occurs when photons (particles of light) strike a metal surface and transfer enough energy to knock electrons off the surface. These ejected electrons form an electric current. Options A, B, and C do not accurately describe the process of the photoelectric effect.

Answer:

D. Electrons are knocked off the surface that the light strikes by "particles" of light.
