# Which is the longitudinal wave?

## Which is the longitudinal wave?

longitudinal wave, wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave. The combined motions result in the advance of alternating regions of compression and rarefaction in the direction of propagation.

### What is sound wave called a longitudinal wave?

The vibration of medium that travel along or parallel to the direction of wave is called a longitudinal wave. In a sound wave, the particles of the medium vibrate in the direction parallel to the direction of propagation of disturbances. Hence, a sound wave is called a longitudinal wave.

#### What type of wave is sound wave?

longitudinal waves
So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

Is a sound wave transverse or longitudinal?

Longitudinal And Transverse Waves : Example Question #5 Explanation: Sound is a longitudinal wave, while light is a transverse wave. Polarization requires the direction of the wave to be perpendicular to the direction of propogation; only light can do this.

Solution : Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave.

## Why is sound wave called a longitudinal wave short answer?

A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it. The air particles vibrate parallel to the direction of propagation.

### What is longitudinal wave Class 8?

#### What is the top of a longitudinal wave called?

Key terms

Term (symbol) Meaning
Periodic wave Wave that repeats over time and space. Also called a continuous wave.
Crest Highest point on a transverse wave. Also called the peak.
Trough Lowest point on a transverse wave.
Expansion A point of maximum spacing between particles of a medium for longitudinal waves.

What are sound waves physics?

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person’s vocal chords.

Is sound wave is transverse wave?

Sound can propagate through a medium such as air, water and solids as longitudinal waves and also as a transverse wave in solids. The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker.

## What is transverse wave and longitudinal waves?

Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
