Answer Details
The main factor that affects the speed of sound waves is the properties of the medium. The speed of sound is a measure of how fast sound waves travel through a particular medium, such as air, water, or solid objects. The speed of sound in air, for example, is approximately 343 meters per second at room temperature and normal atmospheric pressure.
The properties of the medium affect the speed of sound waves because sound waves travel by compressing and expanding the particles in the medium through which they are propagating. The speed of sound waves is determined by the density, compressibility, and temperature of the medium. In general, sound waves travel faster through denser and less compressible media, and at higher temperatures.
Therefore, the correct answer to the question is "properties of the medium." The amplitude, intensity, and loudness of the sound wave do not directly affect the speed of sound, although they can influence the perception of the sound by the human ear. Amplitude is a measure of the maximum displacement of the particles in the medium, intensity is a measure of the power of the sound wave per unit area, and loudness is a subjective measure of how loud the sound is perceived to be by an observer.
