Question

question 18 of 25 what did the photoelectric experiment demonstrate? a. light can heat metal enough to produce electricity. b. light can cause electrons to be released from the surface of a metal. c. light can make metal atoms move around, producing electricity. d. light can deposit electrons on a metal surface.

Explanation:

The photoelectric effect is the phenomenon where light (photons) incident on a metal surface causes electrons to be ejected from the metal. It does not involve heating the metal to produce electricity, making metal atoms move to produce electricity, or depositing electrons on the metal surface.

Answer:

B. Light can cause electrons to be released from the surface of a metal.
