8.PS4.1 Study Guide

Front

What is a wave?

Back

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

Front

What is frequency in relation to waves?

Back

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

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

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

Front

What are transverse waves?

Back

Transverse waves are waves in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the motion of the medium is parallel to the direction of the wave's travel.

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where the particles of the medium are closest together.

Front

What is a rarefaction in a longitudinal wave?

Back

A rarefaction is a region in a longitudinal wave where the particles of the medium are spread apart.

Front

How do you compare the frequency of two waves?

Back

To compare the frequency of two waves, observe how many wave cycles pass a point in a given time; the wave with more cycles has a higher frequency.

Front

What is the relationship between wavelength and frequency?

Back

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