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.
The speed of sound cannot be measured in a vacuum because there is no medium for sound waves to travel through in a vacuum. Sound requires a medium such as air, water, or solids to propagate.
Sound cannot travel through a vacuum as it needs a medium, such as air, water, or solid material, to propagate. In a vacuum, there are no particles for sound waves to travel through, so the speed of sound is essentially zero.
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
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
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.

The speed of light in a vacuum is constant and does not depend on external factors like temperature. However, when light passes through a medium other than a vacuum, such as air or water, its speed can be affected by factors like the refractive index of the medium.

The speed of sound does not depend on the wavelength or frequency of the sound wave. It is mainly determined by the properties of the medium it travels through, such as temperature and density.
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.
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.
