What wave moves back and forth?

Longitudinal Waves. In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions.

What type of medium can a mechanical wave move through?

A mechanical wave is a disturbance in matter that transfers energy through the matter. The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves.
• Do transverse waves need a medium to go through?

Electromagnetic (EM) waves (such as light) are also transverse waves but they do not require a medium and thus can pass through a vacuum (see intro).They consist of oscillating electric (E) and magnetic (B) fields which are perpendicular to the direction of propogation while also being mutually perpendicular.
• Can electromagnetic waves travel through a medium?

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
• Do sound waves need a medium to travel?

That's because sound is a mechanical wave. In contrast, electromagnetic waves require no medium, but can still travel through one. Since a vacuum is defined as lacking a medium, then sound and correspondingly, mechanical waves, cannot propagate through a vacuum. This is why we can't hear voices or sounds in space.
B.

What medium can a mechanical wave move through?

A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
• What are the two main types of mechanical waves?

Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.
• How is a mechanical wave created?

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
• Is a mechanical wave a light wave?

Most of the mathematics and properties of mechanical waves apply to light waves. Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave.
C.

Why do mechanical waves need a medium to travel through?

Electromagnetic waves do not require a medium in order to transport their energy. 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. That is, mechanical waves cannot travel through a vacuum.
• Why do mechanical waves propagate through a medium?

An ocean wave will transport ocean water from near the middle of the ocean to a location near the shore. 5. As mechanical waves move through a medium, particles of the medium undergo a periodic and repeated vibration about a fixed position. Mechanical waves propagate or move through a medium because ________.
• How does sound travel through a medium?

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. Sound travels about four times faster and farther in water than it does in air.
• What is the medium of a mechanical wave?

A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
