The speed of sound in vacuum is zero. Sound needs a material medium in order to
propagate. Since vacuum contains no material medium, sound does not propagate.
Therefore, it never moves from the source of the sound, and the
Speed = (distance covered in any time interval) divided by (time to cover the distance)
is zero.
Sound can not propagate in a vacuum. Sound waves, unlike light, are essentially compression waves and the sound in order to move from one place to other needs molecules to compress and decompress against, hence the wave is transmitted. In a vacuum, there are no molecules. Hence no sound and no speed of sound in a vacuum. The sound in "Star Wars" the movie is still fun.
it doesnt. It can not. It requires a medium, air for instance.
Sound will not travel in a vacuum, so zero.
Sound waves, by definition, cannot travel through a vacuum.
The medium through which it is propagating. For exampl if the sound waves are travelling in air they will move slower than those travelling through a wall speed of sound in solids > speed of sound in liquids > speed of sound in gases
You'd have to say that the speed of sound waves in vacuum is zero, becausesound can't travel through vacuum at all. Not even an inch. Sound needs amaterial substance to travel through.
It is sound travelling through a dense medium, like iron, for example.
Sound waves cannot travel in a vacuum.
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)

Travelling through a medium that is optically less dense. Vacuum is best.
It is approx 4540 metres/second
Mach is the speed of an object expressed as a multiple of the speed of sound in the same medium. Thus, an object travelling at 686 metres per second through air, at sea level, is travelling at Mach 2 because sound would travel through it at 343 m/s. However, it the object was travelling under water at the same speed then it would be travelling at approx Mach 0.46 since sound travels at 1484 m/s through water.

Electromagnetic waves have the same speed when travelling through a given medium: Air, water, vacuum,...

Travelling faster than the speed of sound causes a loud noise called the sonic boom.
The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower). An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure). BUT In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
