# Quick Answer: How Far Can A Sound Wave Travel?

## Is sound louder underwater?

Sound travels faster in water compared with air because water particles are packed in more densely.

Thus, the energy the sound waves carry is transported faster.

This should make the sound appear louder..

## Which material does sound travel fastest?

solidsSound travels over four times faster than in air! Sound travels fastest through solids. This is because molecules in a solid are packed against each other.

## How far can light travel before it stops?

In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. This is why light from distant stars can travel through space for billions of light-years and still reach us on earth.

## Is it possible for anything to travel faster than the speed of light?

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

## How long does it take sound to travel 100 miles?

68 secondsAssuming you use the speed of 760 m.p.h. at ground level to equal Mach 1, rounded to the closest second, it would take 68 seconds to cover 100 miles.

## How many seconds does it take for thunder to travel a mile?

5 secondsSince you see lightning immediately and it takes the sound of thunder about 5 seconds to travel a mile, you can calculate the distance between you and the lightning.

## How far can the sound of the ocean travel?

Sound waves can be trapped effectively in the narrow SOFAR channel. Traveling at minimum velocity, the sound waves lose little energy, allowing the waves to propagate over distances in excess of 25,000 kilometers (15,500 miles).

## Can light travel forever?

Light is a self-perpetuating electromagnetic wave; the strength of the wave can get weaker with the distance it travels, but as long as nothing absorbs it, it will keep on propagating forever.

## Is light or sound faster?

Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.

## Do sound waves travel faster at night?

During the day the sound travels faster near the ground. This causes the sound wave to refract upwards. At night the opposite happens. The sound further from the ground travels faster at night causing the sound wave to refract back towards the earth.

## Does the sun make noise?

The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!

## Why does noise carry at night?

You may wonder, it is because it is quieter at night than in the daytime. … Actually, sound transmits farther at night may be related to refraction of sound waves! First, sound is the vibration of air, and it is a kind of wave motion. The propagation of sound wave is faster in hot air and slower in cold air.

## Do sound waves go on forever?

Sound waves do not live forever. … As the energy of the sound is transferred to more and more molecules of air, they vibrate less and less until the effect is lost in the constant random jostle of air molecules. The sound is gone.

## What can sound not travel through?

We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.

## Why can’t astronauts hear each other in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

## How fast does sound of thunder travel?

about 340 meters per secondThunder travels at the speed of sound and has a value of about 340 meters per second. The speed of sound in air at sea level moves about 1 mile every 5 seconds. Thus, when you see the lightning count the seconds and divide by 5 to get the approximate distance that the sound of thunder originates from.

## Does sound travel faster in saltwater or freshwater?

Sound and Salinity In seawater, sound travels up to 33 meters per second faster than in freshwater.

## Does sound travel faster underwater?

While sound moves at a much faster speed in the water than in air , the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.

## How does sound travel over long distances?

A sound channel exists in the ocean that allows low-frequency sound to travel great distances. This channel is called the SOund Fixing And Ranging , or SOFAR, channel. … On the right is shown only the paths sound travels from a source at 1000m depth to a receiver at 1000m depth that is 210km away from the source.

## How long does it take for sound to travel 1 mile?

five secondsIn air at a temperature of 70° F (22.2° C), sound travels at a speed of about 1,129 feet (344 meters) per second, which is roughly equivalent to one-fifth of a mile in one second, or one mile in five seconds (or one kilometer in about three seconds).

## Does sound waves travel in vacuum?

Sound waves are travelling vibrations of particles in media such as air, water or metal. … So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
