Flashcards

Amplitude

The maximum displacement of a point on a wave from its equilibrium position.

Period (T)

The time taken for one complete oscillation of a wave, or for one full wavelength to pass a given point.

Frequency (f)

The number of complete oscillations or wavelengths passing a point per second.

Wavelength (λ)

The distance between two consecutive points in phase on a wave, such as between two crests or two troughs.
