Answer:
1. Amplitude.
2. Rarefaction.
3. Wavelength.
4. Compression.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission. Some of the properties of sound waves as it travels through a medium such as solid, liquid and gas includes the following;
1. Amplitude: the density of the medium's particles at the compressions of the waves.
2. Rarefaction: the part of a wave where the particles of the medium are farther apart. This ultimately implies that, it is part of a longitudinal wave in which the particles that make up the matter for the movement of the wave are separated by a greater distance.
3. Wavelength: the distance between compressions or rarefactions i.e the distance between two successive compressions or refractions.
4. Compression: the part of a wave where the particles of the medium are closer together. This ultimately implies that, it is part of a longitudinal wave in which the particles that make up the matter for the movement of the wave are closer together.
