Lecture

Photoelectric Effect: Fun Science Project

Description

This lecture presents a fun science project demonstrating the photoelectric effect using an electroscope, zinc metal electrode, and ultraviolet light. By observing the movement of aluminum foil leaves, the instructor explains how photons of ultraviolet light cause electrons to break free from zinc atoms, leading to a decrease in negative charge and the gradual coming together of the leaves. The experiment showcases the principles of the photoelectric effect and its impact on the behavior of charged objects.
