Wave Function

Waves transfer energy without permanently moving matter; particles oscillate in place.

Medium Particles in Wave

The particles vibrate around their equilibrium positions, passing energy to neighboring particles.

Wave Amplitude

Amplitude measures the maximum displacement of a wave from its resting position, indicating wave intensity.

Wavelength

Wavelength is the distance between identical points (e.g., crests) on adjacent waves.

Sound wave in air

Sound waves transmit energy through the air via compressions and rarefactions, reaching the ear without air displacement.
