Amplitude
Definition
Amplitude refers to the maximum displacement or distance from equilibrium position that a particle in a wave moves. It represents the energy carried by the wave.
Analogy
Think of amplitude as how high you can jump on a trampoline. The higher you jump, the greater your amplitude. Similarly, in a wave, the greater the amplitude, the more energy it carries.
Related terms
Intensity: The amount of energy per unit area carried by a wave.
Crest and Trough: The highest and lowest points respectively on a transverse wave.
