# Quick Answer: Do Sound Waves Travel Forever?

## Does sound travel faster in water or air?

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..

## Is anything faster than light?

Nothing can move faster than the speed of light. When Einstein set forth his theory of relativity, this was his inviolable postulate: that there was an ultimate cosmic speed limit, and that only massless particles could ever attain it. All massive particles could only approach it, but would never reach it.

## Does light ever end?

Answer 2: No, in fact light only stops when it is absorbed by an electron in an atom of an object. Light in a perfect vacuum travels on at its full speed until it hits something.

## How long do sound waves travel?

Sound waves can travel through any material, but not in a vacuum, which is why there is no sound in outer space. The speed of sound in air is about 330 m/s, meaning that it covers a mile in about five seconds.

## Do sound waves carry on forever?

A small amount of mass is transported along with all sound waves, according to a new theory. Ordinary sound waves carry a small amount of mass with them as they travel, according to a new theoretical study. … For a 1-second-long, 1-watt sound wave in water, the amount of mass would be about 0.1 milligrams.

## Can light travel forever?

As long as it doesn’t get absorbed by something, then yes, light will continue to travel indefinitely. However, due to the expansion of the universe that light wave will get stretched out along with the space it travels through, becoming lower in frequency and energy.

## Does sound travel faster than light?

The speed of sound through air is about 340 meters per second. … Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales. No information can propagate faster than the speed of light.

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

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. … Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut’s whistling can’t travel over to the other astronaut’s ears.

## What sound frequency can kill humans?

7 hzThe most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.

## Does sound ever stop traveling?

Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). As the particles in the medium vibrate, energy is lost to heat, viscous processes, and molecular motion. So, the sound wave gets smaller and smaller until it disappears.

## Do waves carry matter?

It is important to remember that all waves transfer energy but they do not transfer matter .

## Does light have a distance limit?

With the highest speed it travels as far as possible till it gets stopped by something opaque or something absorbs it so that it trasfers its energy to that thing (for example an electron). So there you go… there is no limit of the distance to be covered.

## Why does the energy in a wave eventually die out?

A wave as seen above will start losing energy by transferring it to kinetic and rotational energy at the shallow bottom including sand transfers, which finally will become heat (extra kinetic energy). … A wave hitting a rocky precipice will be transferring vibrations (finally heat) but also will erode part of the rock.

## Which material does sound travel fastest?

solidsOf the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids.

## Do sound waves ever die?

To answer your question, yes. Sound waves do die out after a while. … When this vibrational energy is absorbed by objects in space, the energy of the wave starts reducing ultimately making is so low that the resulting sound is inaudible, and the sound finally dies out.

## What can sound not travel through?

vacuumSound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

## What is the evidence that sound travels as a wave?

What is the evidence that sound transport energy? Sound is a type of wave and therefore transports energy as any other wave. For example, sound can cause objects to vibrate, which is evidence that sound is a form of energy.

## What was the loudest sound on earth?

KrakatoaKrakatoa is believed to be the loudest sound produced on the surface of the planet — in human history, that is. It circled the Earth four times in every direction and shattered the ears of sailors 40 miles away. The Krakatoa volcano erupted with ungodly strength, sending ripples of sound heard thousands of miles away.

## Can sound travel underwater?

Sound that’s generated underwater stays underwater; very little sound passes from water to air. When your head is out of the water and you listen to a sound made underwater, you don’t hear much. But if you put your head under the water, the sound becomes much louder.

## How far can you hear the ocean?

How far you can hear the sea depends on how quiet the area is, and the sensitivity of an ear or microphone. 6km is probably not feasible for most people though. In a gale, wind noise would smother it. In calm conditions, the sea doesn’t make much noise to start with.

## Why do sound Cannot travel through vacuum?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.
