Unit 1 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

Mechanical waves and electromagnetic waves.

Front

What is the amplitude of a wave?

Back

The amplitude is the maximum distance that the wave moves from its rest position.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is the relationship between frequency and wavelength?

Back

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

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

What type of wave can travel through a vacuum?

Back

Electromagnetic waves can travel through a vacuum.

Front

What is visible light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye.
