8.2.4: Waves

Front

What is the definition of a wave?

Back

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

Front

What is wavelength?

Back

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

What is amplitude?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

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 is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

How does energy relate to waves?

Back

Waves carry energy as they travel through a medium, but they do not carry matter.

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.

What is the formula for wave speed?

Back

Wave speed = Wavelength x Frequency.

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through (like sound waves), while electromagnetic waves do not (like light waves).
