Wave properties refer to the characteristics that define how waves behave and interact with their environment. Key properties include wavelength, which is the distance between successive peaks of a wave, and frequency, the number of waves that pass a point in one second. These properties help determine the energy and speed of the wave. Another important property is amplitude, which measures the height of the wave from its rest position. This indicates the wave's energy; higher amplitude means more energy. Waves can also exhibit behaviors such as reflection, refraction, and interference, which describe how they interact with obstacles and other waves.
