1. the maximum extent of a vibration or oscillation, measured from the position of equilibrium
Usage: physics
2. largeness or fullness of extent or size; breadth, width
Usage: formal

Examples

• The sound waves had different amplitudes, creating varying volumes.
• Scientists measured the amplitudes of the earthquake’s seismic waves.
• The pendulum’s amplitude decreased as friction slowed its motion.
• Radio signals with greater amplitudes travel farther distances.
• The amplitudes of the ocean waves increased during the storm.
• We studied the amplitudes of various electromagnetic frequencies.
• The project’s amplitudes exceeded our initial expectations.
