* Higher Amplitude: As the amplitude of the wave increases, the particles vibrate with a greater distance from their resting position. This means they have a larger displacement from their equilibrium point. Think of it like pushing a spring further back and forth – the spring compresses and expands more.
* Greater Energy: Higher amplitude also means the wave carries more energy. This energy is directly related to the vibration of the particles. The more energy, the further they move back and forth.
Examples:
* Sound waves: A louder sound has a higher amplitude, meaning the air particles vibrate with a greater displacement. This is what makes the sound seem stronger.
* Seismic waves: Earthquakes with higher amplitudes cause more severe shaking, as the ground particles have greater displacement.
Key Point: The *frequency* of the wave (how many vibrations per second) does not change the particle displacement, only the *amplitude* does.
