Wave Properties

Frequency (f)

Number of complete wave cycles per second. Measured in Hertz (Hz). Higher frequency = higher pitch for sound.

Wavelength (λ)

Distance between consecutive wave crests (or troughs). Measured in meters. Determines color for visible light.

Period (T)

Time for one complete wave cycle. T = 1/f. Measured in seconds.

Amplitude

Maximum displacement from equilibrium. Determines wave intensity and loudness for sound.
