Question
What happens to electrons in the photoelectric effect?A.They are made to orbit faster.B.They are knocked away from atoms.C.They are turned into light.D.They are added to atoms.
Solution
In the photoelectric effect, electrons are knocked away from atoms. So, the correct answer is B. This phenomenon occurs when light shines on a material, causing it to absorb energy and release electrons.
