-There is zero probability of sound being transmitted though space that is empty of all matter, a vacuum. Sound is by its nature transmission of energy on a medium, variation of pressure.
2. how does the wavelength of sound affect its frequency?
-Since the sounds are travelling at about the same speed, the one with the shorter wavelength "waves" more frequently; it has a higher frequency, or pitch. The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low.
3. what characteristic of sound determined by a.) frequency b.) loudness
-(a) The loudness or softness of a sound is determined by its amplitude. (b) Pitch of the sound is determined by its frequency. Explanation The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
