Waves Review

Front

What is a wave?

Back

A wave is a periodic disturbance that transfers energy through a medium or vacuum.

Front

What is frequency?

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 mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium and can travel through a vacuum, such as light waves.

Front

What type of wave is a sound wave?

Back

A sound wave is a longitudinal mechanical wave.

Front

What type of wave is a light wave?

Back

A light wave is a transverse electromagnetic wave.

Front

How does the speed of a wave relate to its frequency and wavelength?

Back

The speed of a wave is equal to its frequency multiplied by its wavelength (v = f × λ).

Front

What is the relationship between frequency and wavelength?

Back

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