(Q4) Intro to Mechanical Waves

Front

What type of wave are sound waves?

Back

Sound waves are longitudinal waves.

Front

What types of waves are water waves made of?

Back

Water waves are made of both types of mechanical waves.

Front

What does Section A represent in a wave diagram?

Back

Section A represents the direction of disturbance.

Front

What is the term for the lowest point of a wave?

Back

The lowest point of a wave is called the trough.

Front

What is the term for the highest point of a wave?

Back

The highest point of a wave is called the crest.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the disturbance is parallel to the direction of wave travel; in transverse waves, the disturbance is perpendicular to the direction of wave travel.

Front

What is compression in a longitudinal wave?

Back

Compression is the region in a longitudinal wave where particles are closest together.

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the region in a longitudinal wave where particles are furthest apart.

Front

What is the rest position in a wave?

Back

The rest position is the position of the medium when there is no wave passing through.
