8.2.4 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

The two main types of waves are mechanical waves and electromagnetic waves.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (matter) to travel through, such as air, water, or solid materials.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium, such as light or radio waves.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is another name for a longitudinal wave?

Back

Another name for a longitudinal wave is a compressional wave.

Front

Can electromagnetic waves travel through a vacuum?

Back

Yes, electromagnetic waves can travel through a vacuum.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.
