This question is misguided. It is not the sound waves which are apart, but the particles of the medium. A place where the particles are further apart is called a rarefaction. Where they are crowded together is called a compression.
Wavelength.
Interference
The wave length. This is also correct if you are referring to the distance between the trough of two waves.
It is called the wave height.
It is called the shadow zone, an area at an angle of between 104° and 140° from the axis of the epicenter, where the earth's liquid outer core has refracted the P-waves away from the direct line of travel.
The area between deep water waves and breaker zone is the euphotic zone
the interaction between sound waves is called interference.
the distance between the crests of two succesive waves is called the wavelength. It is directly related to the frequency of the wave
