Waves & Sound Review

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through matter or space, characterized by its frequency, wavelength, and amplitude.

Front

What is frequency in the context of waves?

Back

Frequency is the number of complete wave cycles that pass a given point in one second, measured in hertz (Hz).

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

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

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is a node in a standing wave?

Back

A node is a point along a standing wave where the wave has minimal amplitude and does not move.

Front

What is an antinode in a standing wave?

Back

An antinode is a point along a standing wave where the wave has maximum amplitude.

Front

How do you calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: speed = frequency × wavelength.

Front

What is the relationship between frequency and wavelength?

Back

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