Question

What is the relation between amplitude and intensity?

Answer 1

1. The maximum displacement of an oscillating object or a wave from its equilibrium position is known as amplitude.
2. The intensity of a wave can be defined as the energy transferred by it per unit area and per unit time.
3. The intensity is directly proportional to the square of the amplitude of a wave and can be expressed as $I\propto A^2$, where $I$ is the intensity and $A$ is the amplitude.
