Some characteristics of a wave include Amplitude: The maximum displacement of a wave from its equilibrium position. Wavelength: The distance between two consecutive points on a wave that are in phase. Frequency: The number of complete waves passing a point in one second. Period: The time taken for one complete wave to pass a given point. Speed: The rate at which the wave is travelling through the medium. Phase: The position of a point on a wave relative to a fixed point in time. Direction of propagation: The direction in which the wave is travelling.
