# Does water travel faster in water or air?

## Does water travel faster in water or air?

Water is denser than air, so it takes more energy to generate a wave, but once a wave has started, it will travel faster than it would do in air.

### How much louder is sound underwater?

An explosion of 200 decibels, then, is 10 times more intense than the sound of a container ship. Because water is much denser than air, sound travels underwater about four times faster and much farther than above the sea’s surface.

#### Where does sound travel fastest?

solids
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

Why can’t humans hear underwater?

Unfortunately, human beings are unable to hear and decipher lower frequencies because those sound waves require the small ossicles bones. Sound waves cannot tell the difference between your body and the water around you, therefore it travels until it hits something else to vibrate – like your skull.

Why can sound not travel through empty space?

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.

## Is sound louder in water?

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.

### Can sound waves travel in 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.

#### In which metal sound travels fastest?

Steel
Sound travels faster in Steel than any other liquids. In steel, the density and elastic properties are more than other given mediums.

Can humans hear underwater?

On land, humans hear through air conduction. But underwater, humans don’t hear using the normal channels. Instead, the study found that humans hear through bone conduction, which bypasses the outer ear and the ossicles of the middle ear.

Can humans speak underwater?

Special underwater communication systems have been developed to allow divers to talk to each other underwater. A transducer is attached to the diver’s face mask, which converts his or her voice into an ultrasound signal. Acoustic communication systems allow divers to talk to each other underwater.

## What can sound not travel through?

vacuum
Sound 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.

### Why is space silent?

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum.
