What causes particles to move back and forth along the same direction in which the wave travels?

What causes particles to move back and forth along the same direction in which the wave travels?

As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward.

What wave makes particles move back and forth?

longitudinal wave
In a longitudinal wave, particles of the medium vibrate back and forth parallel to the direction of the wave. In a surface wave, particles of the medium vibrate both up and down and back and forth, so they end up moving in a circle.

Which type of wave does the earth move back and forth along the same direction as the wave travels?

compressional wave
In a compressional wave, matter in the medium moves back and forth along the same direction that the wave travels. You can model compressional waves with a slinky. Squeeze several coils together at one end of the spring.

What is matter moves in same direction as wave travels?

In a compressional wave, matter in the medium moves forward and backward along the same direction that the wave travels.

What do waves carry from place to place?

A wave is a disturbance that transfers energy from one place to another without transferring matter. Waves transfer energy away from the source, or starting place, of the energy.

When a wave moves what happens to the medium?

Q: How do the particles of the medium move when a wave passes through them? A: The particles of the medium just vibrate in place. As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on.

What part of the wave carries the energy?

amplitude
The amount of energy carried by a wave is related to the amplitude of the wave. A high-energy wave is characterized by a-high amplitude; a low energy wave is characterized by a-low amplitude. Putting a lot of energy into a transverse pulse will not affect the wavelength, the frequency or the speed of the pulse.

What are two types of waves that require matter in order to travel?

Compare and contrast two kinds of waves: mechanical (which require a medium of matter to move through), and electromagnetic (which do not require a medium of matter to move through).

Which is the second type of mechanical wave?

A second type of mechanical wave is called a compressional wave. This type of wave causes particles in matter to move back and forth along the same direction the wave travels. You can think of a compressional wave as a slinky going back and forth. The areas that are squeezed together are called compressions.

How is the amplitude of a transverse wave determined?

In a transverse wave, the amplitude is half the distance between the crest and trough. In a compressional wave, the amplitude depends on the density of the material and the length of compressions and rarefactions. A wave with a higher amplitude has more compressed compressions and more spread out rarefactions.

What are the crests and troughs of a transverse wave?

Transverse waves are mechanical waves that can have, but do not need, a medium. It causes particles in matter to move move back and forth at right angles to the direction it travels. These waves have high and low points, called crests and troughs. This series of crests and troughs makes the transverse wave you see in the image below.

Why is the amplitude of a compressional wave higher?

In a compressional wave, the amplitude depends on the density of the material and the length of compressions and rarefactions. A wave with a higher amplitude has more compressed compressions and more spread out rarefactions. In sound waves a higher amplitude means a louder sound.
