Parts and Properties of Waves 12.18

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 main parts of a wave?

Back

The main parts of a wave include the crest (highest point), trough (lowest point), wavelength (distance between two crests), and amplitude (height of the wave from rest position).

Front

What is frequency in relation to waves?

Back

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

Front

How does frequency affect energy in a wave?

Back

As the frequency of a wave increases, its energy also increases.

Front

What is amplitude?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the wave's energy.

Front

What is wavelength?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave's travel.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance the wave travels in a given amount of time, calculated as speed = wavelength x frequency.
