Intensity
Intensity explained in an easy to understand way:
Imagine you're trying to pour a large pot of soup into several small bowls without spilling. Just like you need to control how much soup goes into each bowl at a time, the intensity of a wave refers to the amount of energy passing through a specific area in a given second. In this analogy, the soup is like the wave's energy, the bowls are the areas it passes through, and your careful pouring determines how much energy—or soup—is delivered to each bowl in a second, illustrating how intensity measures energy distribution.
Practice Version
Intensity: The amount of energy a wave carries through a unit area in one second. Intensity. Intensity is the measure of how much energy passes through a given area in a specific time period.
