Final answer:
Two important characteristics of waves are amplitude and wavelength. Waves can also exhibit interference and vary in intensity.
Step-by-step explanation:
Two important scientific characteristics of waves are amplitude and wavelength. The amplitude of a wave is the distance from the center line to the top or bottom point of the wave. The wavelength refers to the length of the wave from one peak to the next. These characteristics can be found in mechanical waves, which also exhibit other common wave properties such as period, frequency, and energy. Another important characteristic of waves is interference, which is observed when a wave interacts with an object. Interference is prominent when the object is not large compared to the wavelength of the wave. Waves can also vary in intensity, which can be concentrated or spread out, and it affects the area the waves cover and their effects.
