Properties 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

Mechanical waves and electromagnetic waves.

Front

What is a crest in a wave?

Back

The crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

The trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum distance that points on a wave move from their rest position.

Front

How does frequency affect wavelength?

Back

As frequency increases, wavelength decreases.

Front

What is the relationship between frequency and energy?

Back

Higher frequency waves carry more energy.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.
