The speed of sound depends on the properties of the medium, such as its density and composition, elastic properties and dispersion (dispersion basically refers to the property that some media allow different frequency components of a sound wave to travel at different speeds). And some of those properties - like density, for a compressible medium such as air - are themselves dependent on other variables like temperature, pressure, etc. For example: The speed of sound in dry air at 20 C (68 F) at sea level is approximately 343 metres per second (1235 km/h or 770 mph) (values quoted from wikipedia) The speed of sound in an a very stiff medium such as steel is roughly 4500 metres per second. (Temperature does not have a dramatic effect on speed because steel is essentially incompressible when compared with a gas) In a vacuum (e.g. a void in deep space), there is no speed of sound because there are essentially no closeby particles to form a medium through which sound waves can propagate Note that contrary to intuition, the speed of sound generally decreases with increasing density of the medium (i.e. the two are inversely related).

Compare the speed of light to the speed of sound?

Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger. However, sound has very different speeds, depending on the medium in which it travels.Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger.

How many times faster is the speed of light in a vacuum than the speed of sound air?

100% - sound is vibration of atoms/molecules - it cannot travel through vacuum ___________________________ The idea of "speed pf sound in a vacuum" is meaningless; sound cannot travel without a medium such as air, water, metal, stone, or SOMETHING. Sound waves are mechanical vibrations; there has to be something to vibrate. The speed of sound in air is around 700 miles per hour, while the speed of light is 186,000 miles per SECOND.


What is mach 8?

Mach 8 is a unit of speed equal to 8 times the speed of sound. At sea level and room temperature, the speed of sound is approximately 761 mph (1,225 km/h). Therefore, Mach 8 would be around 6,088 mph (9,800 km/h).


What is twice the speed of sound called?

Twice the speed of sound is called Mach 2. This means an object is traveling at twice the speed of sound, around 1,522 miles per hour at sea level.


What is mach speed?

340.29 m/s

What does Mach 25 mean?

Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.


How fast is Mach 1 Mach 2 Mach 3 Mach 4 etc to the fastest Mach level on record?

The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.


How many times faster than the speed of sound can you travel?

No real limit, up to the speed of light. The Apollo astronauts traveled at ABOUT 32 times the speed of sound on their trip to the moon. That is the fastest yet.

How is the speed of light and speed of sound related?

The speed of light is about 900,000 times as fast as the speed of sound in air.

How did the Concorde speed compare with the speed of sound?

The Concorde's cruising speed was over twice the speed of sound, around Mach 2 (more than 1,300 mph). The speed of sound at sea level is approximately 761 mph, so the Concorde flew significantly faster than the speed of sound.


How fast is mach1?

Mach 1 is one times the speed of sound, which equals the speed of sound, which is 768mph.


Does light travel at half the speed of sound?

No. Light travels at about 875 thousand times the speed of sound.


What is 96mach?

0.96 mach is 96% the speed of sound. Mach 96 would be 96 times the speed of sound.
