# How Fast Can Sound Travel?

Sound travels through air at a speed of around 332 metres per second. The speed of light is 300 000 kilometres per second, which is faster than this, but not quite as fast as this. It is because of this contrast in speeds that we can comprehend the fact that sound travels at a slow pace.

## What’s the fastest sound can travel?

It took scientists 22 miles (36 kilometers) per second to uncover the fastest conceivable speed of sound, which was previously thought to be impossible. Sound waves travel at varying rates in different states of matter, including solids, liquids, and gases, as well as within those states of matter — for example, sound waves travel faster in warmer liquids than they do in colder liquids.

## How fast does sound actually travel?

When a sound wave propagates across an elastic material, the speed of sound is defined as the distance traveled per unit of time by the wave.At 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound in air is approximately 343 metres per second (1,125 feet per second; 1,235 kilometers per hour; 767 miles per hour; 667 kilometers per hour), or one kilometre in 2.9 seconds and one mile in 4.7 seconds.

## Can sound ever travel faster than light?

As a result, they are on completely different scales. There is no way for information to spread faster than the speed of light. Alternatively, if you have light traveling through a medium, it can travel more slowly than that. However, the speed of sound and the speed of light are incomparably different.

## How fast is sound in water?

In water, sound travels at a quicker rate than it does in air. The speed of sound in air is approximately 343 meters per second under normal conditions, whereas the speed of sound in water is approximately 1,480 meters per second under normal conditions. Basic to sound is the compression wave passing through the substance that it is produced by.

## How fast is the speed of dark?

The speed of light is equal to the speed of darkness. A more realistic definition of darkness is that it is just the absence of light, rather than a distinct physical entity in and of itself.

## How far does human voice travel?

Under ideal conditions, the male human voice has a range of around 180 metres while remaining understandable. If you double the distance between you and the speaker, the sound pressure level typically decreases by six decibels, thus you may still be able to hear their voice even if you are unable to comprehend what they are saying at 360 metres away.

## Does sound travel faster in cold air?

When it comes to temperature, sound waves move more quickly in warm air and less quickly in cold air. As a result, as sound travels through the atmosphere, certain portions of the wave will travel at a quicker rate than others.

## Why can sound not travel through empty space?

Sound waves are traveling vibrations of particles in a medium such as air, water, or metal that travel at a constant speed. This means they cannot go across empty space, because there aren’t any atoms or molecules to vibrate and cause them to fly faster.

## What is the fastest thing in the universe?

The speed of light in a vacuum is the fastest thing that exists in the cosmos. In the universe, nothing can go faster than the speed of light, which is equivalent to 3 x 108 meters per second.

## Is lightning faster than the speed of light?

1 C (the speed of light in vacuum) is equivalent to 874,030 Mach (the speed of light in air). When compared to the average lightning speed, light travels at a rate of 675.45 times quicker.

## Is lightning slower than sound?

At the same time, lightning and thunder may be heard. However, you will see lightning before you will hear thunder since light travels a million times quicker than sound and hence comes practically instantaneously when it does. For comparison, it takes around five seconds for sound to travel one mile.

## How fast is light speed?

Light from a stationary source travels at a speed of 300,000 kilometers per second (186,000 miles per second).

## Is there sound in space?

No, you will not be able to hear any noises in near-empty parts of the universe. The oscillation of atoms and molecules in a medium causes sound to move through it (such as air or water). Sound cannot travel in space because there is no air to carry it.

## How fast do light waves travel?

In its travels through air and space, the speed of light is far quicker than the speed of sound; it travels at a speed of 300 million meters per second, or 273,400 miles per hour. In addition to traveling through air and space, visible light may travel through a variety of different materials.
