Waves Unit Review

Front

What is a wave?

Back

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

Front

Define wavelength.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How does energy relate to amplitude in a wave?

Back

Higher amplitude means more energy in the wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, such as light and microwaves.

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).
