Amplitude
The energy in a wave.
Video: Amplitude simple definition.
Imagine trying to communicate with someone across a crowded room at a party. The louder you speak, the more intense your voice becomes, allowing it to travel further and be heard over the ambient noise. Similarly, in a wave, the amplitude represents the energy it carries, determining how far and effectively that energy can travel. Just as speaking louder helps your voice reach the listener, a wave with a higher amplitude has more energy, enabling it to transmit its effects over greater distances.
