A wave simply travels through the medium.

Think of it this way: Radio waves are permeating every cubic inch of our planet every second of the day, moving from the radio tower to your radio, yet the air through which those waves are moving is not coming directly to your radio; the air is staying relatively still while the waves move through it to get to you.

Or, think of it this way: If you're inside, when the radio waves travel through your wall to reach your radio, your wall does not come flying towards your radio with the waves; it stays where it is and the waves pass through it.

What medium does a wave travel in?

There are two types of waves, mechanical and electromagnetic. Mechanical waves need to have a medium to go through in order to even exits. these mediums can include water, dirt, air, metal, glass, plastic, wood, etc. electromagnetic waves travel through just about anything and do not have to have a medium to exist. Hope this helps T.M.M :-)


Why does a sound wave travel the slowest in a vacuum?

Sound waves don't just travel the slowest in a vacuum, they don't travel at all. The reason is that sound waves, like all mechanical waves, need a medium to travel through.


Does Light travels in waves and sound is a form of energy that travels in mechanical waves through a medium?

Sound is a form of energy that travels "through" a mechanical medium. Light can be modelled as waves in certain circumstances. No mechanical medium is detectable, so either there is no medium, or the medium also propagates all matter the same way (Lorentz aether). The photoelectric effect shows that, just like sound is just motions of particles, so is light. electromagnetic


What factors are necessary for a sound wave to travel through a medium?

well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another


Can sperm travel through air?

No, sperm use a small whip-like tail to travel through a liquid medium. Also not just any liquid medium, it must be rather viscous for optimal travel, like that found in semen. The tail would be useless in air.


Why is it not possible to measure the drift speed for electrons by timing their travel?

Because the electrons move in a zig zag pattern through the medium through which they travel they do not just move in a straight line


How well does sound travel through a solid?

its the best medium that sound can travel through,the next is liquid and the slowest is gas the reason for this is because First, sound is mechanical energy. It needs a medium to travel through. The energy is transferred into the medium, and the medium carries it through itself. That's propagation, and you probably already knew most or all of that. But we need to start at the beginning, so let's jump.When something moves to create sound, either continuously like a guitar string, or "just once" like when a hammer strikes a nail head, the action creates pressure waves or a pressure wave. The pressure wave or waves are actually atoms or molecules "pushing against" each other in response to the action causing the sound. The "pushing against" each other is the transfer of the mechanical energy of sound through whatever is "conducting" that energy. That's how sound is transmitted (and why sound can't travel through a vacuum). The medium is carrying the mechanical energy of the wave. So the action of atoms or molecules shoving each other "over" to conduct the sound, this compression of them, has an opposite action, which we call rarifaction.


How do particles move when a mechanical wave passes through them?

the particles of the medium just vibrate, or move back and forth or up and down in one spot


Does electromagnetic waves require a medium to travel through?

Electro magnetic waves do not require a medium to travel. Some scientists believe, however, that all "empty space" is filled with a mass-less medium called ether. This is just a hypothesis however and remains unproven.

Is vacuum the only medium for light to travel?

No. Light also travels through air, water and glass, to give just a few examples.


Can a sound wave travel through a vacuum?

No, because in order for there to be sound there has to be vibrations of the air In a perfect vacuum there is not atmosphere or air of any kind so, therefore, no sound. Sound needs a medium through which to travel, sound cannot travel through a vacuum. No, since sound waves need a medium to propagate themselves such as air or water.Explosions in vacuum only have sounds in Hollywood movies just to enhance the viewer experience. No,'cause in the vacuum,there is no medium to reflect soundwave. No.


What is the best explanation for why sound does not travel through space?

Sound waves require a medium or some sort of atmosphere to pass through, while space is just a vacuum and has neither


How does sound travel through liquid?

The same way as it travels through a gas or a solid. Sound waves are just vibrations travelling through a medium (solid; liquid; gas) and liquids such as water are just as good (actually better in this case) candidates for it as is air. This is also of course the reason there's no sound in space - there's no medium for the sound to exist as (after all - sound is a property of a medium).


Can radio waves travel through air?

Of course, they are similar to visible light waves, just a different wavelength and frequency. Indeed, many electromagnetic waves (radio waves) can travel through solid objects and water depending on the frequency and the medium through which they travel. If radio waves couldn't travel through the atmosphere, your radio wouldn't receive a signal, hence no music.


Do sound waves are electromagnetic waves that do not require a medium to travel through?

The difference between sound waves and electromagnetic waves is that they travel through different mediums, in different ways, though some of those can be the same medium. The main difference is that electromagnetic waves can travel through a vacuum. But to be precise, a vacuum is, itself, a medium. It may be devoid of matter, but that does not mean that it is truly empty. It is actually filled with particles called Higg's bosons. Also, the discussion that physicists are having about exactly how electromagnetic waves travel and what kind of medium it is that they travel through is still in debate and may prove to be the most fascinating frontier of 21st Century physics, just like Einstein's Theory of Relativity revolutionized the 20th Century.


Can sound waves travel through lasers?

Yes. The laser beam is a beam of coherent light. Just photons. Meanwhile the sound wave is travelling through a medium....which isn't really true of the photons, they'll travel whether there's a medium or not. There's essentially no interaction or interference between the two. Saying that I can think of ways you could detect sound waves using lasers...but I wouldn't worry about that - sound will travel just fine through a laser beam providing it still has a medium to travel through. i.e: a laser can be present in a strong vacuum but sound won't pass through a strong vacuum - at least not to any useful degree....but that's not the laser stopping it.


How do sound waves transmit energy?

Sound always propogates through a medium, such as air, water, rock, etc. When something creates a sound, it generates compression waves in the medium. These compression waves travel through the medium, usually without disturbing the medium itself. The compression waves themselves carry energy, just as waves on an ocean carry energy.


Why do transverse waves not need a medium?

Wrong.Earthquake S-waves are just one example of transverse waves that do need a medium to travel through. Specifically they need a solid medium and cannot not travel through either liquid or gaseous mediums.Perhaps you are confusing transverse waves in general with electromagnetic waves (which happen to be transverse) but do not need a medium because they are a propagating electric field - magnetic field each creating the other in a cycle.


When is the only time that light waves travel at thespeedof light?

Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.


If the wind blows at the speed of light can light travel through it?

Since you have already postulated the fantasy that the wind is blowing at the speed of light, you might just as well go ahead and decide whether or not you want light to be able to travel through it, then wave the same wand and make it so. There's no evidence that motion of a material medium has any effect on the ability or inability of light to pass through it, so a first pass at this sorcery produces the speculation that the light would have no problem.


How does sound travel through a slinky?

Sound does not travel through a slinky. This is just a science experiment to SHOW how soundwaves travel.


How sound waves travel through a material?

Vibrations travel through the material, just as they would in air. How well they travel through depends on the material.


Do visible light rays need a medium in which to travel?

No. Not just light waves but all forms of Electro Magnetic Radiation (EMR) are able to travel through vacuums. e.g gamma rays, radio waves, x-rays, etc.


How does sound travel?

Sound (a sound wave) is mechanical energy. The source of the energy, whatever it may be, will transfer mechanical energy into the medium through which it will travel to give rise to sound. It's just that simple. The wave associated with the movement of the mechanical energy of sound is a longitudinal wave. The medium is moved back and forth along the path of travel of the wave. Let's look at an example to try and make things clearer.Picture a speaker cone. The cone moves out and in to create sound waves. When it moves out, it compresses the air in front of it. This compression wave is a volume of "denser air" in the front of the speaker that moves out away from the cone. As the cone comes back in, it creates a volume of "less dense air" behind it called a rarefaction wave. This rarefied air wave will move out away from in front the speaker in the same way the compression air wave did. In this way, the mechanical energy of sound is transfered into the air to create alternating waves of compression and rarefaction. And it is by the mechanism of those waves (sometimes called vibrations) that sound moves through air.Sound also moves through liquids and solids by the same mechanism, but the material of the medium cannot move as dramatically as air can. That means that the waves do not create great changes in the density of the liquid and the solid to transfer the mechanical energy into the medium. Additionally, the sound moves faster in those more dense media. Any mechanical energy that can be put into air can be put into any liquid or solid, and the energy moves in the same way.
