    Wave Terminology

    • Term: Displacement

    • Symbol: s

    • Unit: m

    • Definition: Distance from the equilibrium position in a particular direction; a vector, so it can have either a positive or a negative value

    • Term: Amplitude

    • Symbol: A

    • Unit: m

    • Definition: Maximum displacement from the equilibrium position (can be positive or negative)

    • Term: Wavelength

    • Symbol: λ

    • Unit: m

    • Definition: Minimum distance between two points in phase on adjacent waves; for example, the distance from one peak to the next or from one compression to the next

    • Term: Period of Oscillation

    • Symbol: T

    • Unit: s

    • Definition: The time taken for one oscillation or the time taken for wave to move one whole wavelength past a given point

    • Term: Frequency

    • Symbol: f

    • Unit: Hz

    • Definition: The number of wavelengths passing a given point per unit time

    • Term: Wave Speed
