Because sound waves are mechanical vibrations of material matter. You can't

have sound waves in a space where there's no material to vibrate.

What distinguishes electromagnetic waves from mechanical waves?

electromagnetic waves are wave that do not require a material medium for their propagation while mechanical wave requires a material medium for example light wave is an electromagnetic wave it does not require any material medium(depends on air or water)for their propagation i.e even in the absence of air light will still travel... sound wave is a mechanical wave because sound do not travel in a vacuum....


The matter through which a wave transfers energy is called what?

Propagation medium? Though a wave doesn't need a medium to travel or transfer energy (sound waves do, but lightwaves don't). People used to think there was an ether in which light moved, but there isn't.


Is there sound in a vacuum?

No, you can not produce sound in a vacuum. Sound wave needs medium (for example air) to travel unlike electromagnetic wave which can travel through empty space.actually, sound wave does not propagate itself rather it needs a medium by which sound particle can transfer there energy from one place to other, so it seems like moving. for eg. when u throw a stone in water ,some ripples form in water they seems to moving but not. like this sound propagate. hence it requires medium


Is a mechanical wave a sound wave?

Yes, a sound wave is a mechanical wave. Sound waves need a medium (like air) to travel through. The energy of the wave, the mechanical energy, is transferred into the medium through which it is propagated.


Light waves differ fundamentally from either water waves or sound waves because?

light waves do not require a medium to travel through, unlike water and sound waves which both need a medium (water and air, respectively). Light waves are electromagnetic in nature and can travel through a vacuum. They have different wave properties such as wavelength, frequency, and speed compared to water and sound waves.

What is a wave that doesn't require a medium for propagation?

Electromagnetic waves (like light) don't require a medium for propagation, unlike mechanic waves (like sound).


Is it true that longitudinal waves never need a medium to transport the energy?

No, longitudinal waves do need a medium to transport energy. These waves propagate by compressing and rarefying the medium in the direction of the wave's travel, and they cannot travel through a vacuum. For example, sound waves in air are longitudinal waves that require the air medium for propagation.


Why do sound wave require a medium to travel?

Sound waves are mechanical waves that propagate through the vibration of particles in a medium. Without a medium, such as air, water, or a solid, there are no particles for the sound waves to interact with and transmit the vibrations, so the wave cannot travel. Sound waves need a medium to transfer energy and propagate.

What kind of waves are mechanical?

Those waves which required medium for propagation are called mechanical waves. e.g sound waves,they need medium i.e solid liquid or gas ,to propagate. They cant travel through vacuum. hope u understand that!!


Why is the speed of sound slower then the speed of light?

The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.


How does the propagation of light waves in a vacuum relate to the definition of propagation in physics?

The propagation of light waves in a vacuum is the movement of light waves through empty space. In physics, propagation refers to the transmission or spread of waves or energy through a medium. In this context, the propagation of light waves in a vacuum demonstrates the fundamental concept of how waves can travel through space without the need for a material medium.


Is a sound wave a electromagnetic wave in nature?

No, a sound wave is not an electromagnetic wave. Sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel through, while electromagnetic waves can travel through vacuum and do not need a medium. Sound waves are disturbances in a medium caused by vibrations, while electromagnetic waves are fluctuations in electric and magnetic fields.


Which waves can go through a vacuum?

Electromagnetic waves are the only form of energy that does not need a medium for propagation.


Describe an experiment to demonstrate that sound wave require a material for propagation?

To demonstrate that sound waves require a material for propagation, one can set up two rooms with a speaker in one room and a microphone in the other. If there is air or another material between the two rooms, the microphone will pick up the sound waves. However, if the space between the rooms is in a vacuum, the microphone will not detect any sound, showing that sound waves need a medium to travel through.


Sound is reallly an example of?

Sound is really an example of wave propagation of energy. Energy could be transported by two modes. One is by the particles. A good example is electrical energy in the form of current is carried over by the particles such as electrons. The other one is by wave propagation. Wave too is further divided into mechanical and electromagnetic. Mechanical wave badly needs a material medium to get propagated but electromagnetic does not need a material medium. Sound is an example for mechanical wave and light is an example for electromagnetic wave.


How the activity to show that sound requires a medium to travel?

The famous bell jar experiment establishes that a material medium is so essential for sound waves to pass through. An electric bell is covered by a jar. The air inside the jar can be removed by means a vacuum pump. As the pressure inside the jar gets reduced the intensity of sound goes on decreasing and when the pressure becomes very much lower then no sound is heard. Thus the need of material medium for propagation of sound energy has been verified.
