# Does sound always need a medium?

## Does sound always need a medium?

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.

### What happens to sound if there is no medium?

Sound needs a medium for propagation Sound is a form of energy which is transmitted in the form of waves. If there is no medium, then vibrations in an object will not travel through it.

Why does sound need a medium but light does not?

Sound waves need a medium travel as they travel by Compression and decompression of molecules Like that they can travel through the air, water, etc. It’s clear that light waves don’t need medium to travel as we get light from the sun in our planet for it to reach us , it crosses the Voccum of space.

Does light or sound require a physical medium?

We know that light doesn’t need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels. Light contrasts with sound, which travels through the air (or some other material medium).

## What does not require a medium?

electromagnetic waves
These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

### What constitutes the medium in sound?

The mechanical vibrations that can be interpreted as sound can travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium. Sound cannot travel through a vacuum.

Does sound travel through a medium?

Sound is a form of energy produced and transmitted by vibrating matter. Sound waves caused by such vibrations move through a medium (a solid, liquid, or gas) in all directions from their source.

Why does sound require a medium to travel and light does not?

## Do you travel without a medium?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

### Do mechanical waves require a medium?

Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles.

Why does light not need a medium?

What is characteristics of sound?

The five characteristics of sound are amplitude, wavelength, period, frequency, and speed or velocity.

## What kind of medium does a sound wave need?

Sound waves require a medium to propagate, generally its air. Sound waves cannot travel in vacuum. Sound waves are longitudinal waves. Wiki User ∙ 2009-04-25 20:44:43

### Is the medium of sound independent of the medium?

Sound and vibration are both mechanical vibrations of a medium, and thus demand a medium for their travel. Note- they vibrate the medium – they are not independent of the medium as is light. Sign up for more answers ✔️

Why are there no sound waves in space?

The air molecules themselves don’t move across the room, much like a water molecules on one side of a swimming pool do not move to the other side in a wave, it’s the energy that moves through the medium. This is why there is no sound in space, there is no medium for the sound wave to move through.

Why are sound waves more difficult to hear?

The farther a sound wave travels, the more it spreads, this makes it more difficult for us to hear a sound. So the nearer you are to a sound the louder it sounds to us. A sound wave enters the ear and is changed into nerve signals, which are interpreted by the brain.
