Types of Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

In a transverse wave, how does the disturbance move in relation to the wave motion?

Back

The disturbance moves perpendicular to the wave motion.

Front

In a longitudinal wave, how does the disturbance move in relation to the wave motion?

Back

The disturbance moves parallel to the wave motion.

Front

What is an example of a transverse wave?

Back

Light waves and waves on a string.

Front

What is an example of a longitudinal wave?

Back

Sound waves.

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

Can sound waves travel in a vacuum?

Back

No, sound waves cannot travel in a vacuum because they need a medium.

Front

Why do sound waves travel faster in solids than in gases?

Back

Sound waves travel faster in solids because the molecules are closer together, allowing quicker transfer of energy.

Front

What is the medium in which sound travels?

Back

The medium can be air, water, or solid materials.
