# When the particles of a medium are far apart?

## When the particles of a medium are far apart?

In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. Places where particles of the medium crowd closer together are called compressions. Places where particles of the medium spread farther apart are called rarefactions.

### When the particles of a medium are far apart that part of the wave is called a?

4. When the particles of a medium are far apart, that part of the wave is called a rarefaction.

What are medium particles?

The air molecules are the particles of the medium, and they are only temporarily displaced, always returning to their original position.

Are there particles in a medium?

In longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction (respectively) relative to the direction of energy transport. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion.

## What is the area in a longitudinal wave where the particles are close together?

compressions
In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. Places where particles of the medium crowd closer together are called compressions.

### What is the distance between two consecutive troughs called?

The highest surface part of a wave is called the crest, and the lowest part is the trough. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

Why do waves not carry the medium with them as they travel?

Waves carry energy through empty space or through a medium without transporting matter. A medium is a material through which waves can travel. It can be a solid, liquid, or gas. When waves travel through a medium, the particles of the medium are not carried along with the wave.

Do electromagnetic waves need 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. This proved that radio waves were a form of light!

## What do you call the distance between two successive particles that are in phase?

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
