What factors are necessary for a sound wave to travel through a medium?
well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
Explain why the speed of sound changes if the temperature of the medium changes?
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
How are sound waves are affected by their frequency and the medium through which the sound wave passes?
The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.
Why does sound not travel through space?
Sound does move through space. It doesn't move though empty space, i.e. a vaccuum. In outer space there is a vaccuum (though not necessarily a perfect vaccuum).Sound is caused by vibrations in a medium such as air (or water or wood). These vibrations compress and rarefy the medium. The vibrations move through the medium as waves.In a vaccuum, there is no medium thus there is no sound.
What moves backwards and forwards in sound?
The atoms of the particular medium in which the sound is produced moves backward and forwards in sound.
Can a gas act as a medium?
air is a gasair is the usual medium for the propagation of sound wavesConclusion, yes.
The portion of a sound wave where the particles of the medium are pressed together is called?
The region of compression is where all the particles of the medium are closer to each other than usual. In a sound wave that usually means that the pressure in that area of compression is slightly greater than the mean pressure of the material in which the sound wave is traveling.
What is the fact of medium on the speed of sound?
Sound travels at different speeds depending on the medium. Sound will travel the fastest through solids.
Why is the speed of sound slower then the speed of light?
The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.
Do sound waves need a medium?
Yes. Sound wave is a mechanical wave and needs a medium.
What is sound and how it is produce?
Sound is vibrations in a physical medium (usually air). Sound is produced by a release of energy that causes a vibration in the medium. Sound can not therefore be in a place where there is no medium (empty space).

As the temperature of a medium increases the rate of speed of sound through the medium what?
The speed of sound through the medium also increases.
Can you hear sound if no medium is present?
no, because sound is a vibration in air or which ever medium it is in
What factors determines the loudness of sound?
Frequency of the sound wave ?Amplitude of the sound wave ?The temperature of the medium ?The density of the medium ?

Does sound change mediums once it passes through medium?
Yes, sound can change its medium.
