Waves Review

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

The two main types of waves are mechanical waves (require a medium) and electromagnetic waves (do not require a medium).

Front

What is frequency?

Back

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

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

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

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move 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 particles of the medium move parallel to the direction of the wave's travel.

Front

What is the formula for wave velocity?

Back

Wave velocity (v) = frequency (f) x wavelength (λ).

Front

What is the Doppler Effect?

Back

The Doppler Effect is the apparent change in frequency or pitch of a wave in relation to an observer moving relative to the wave source.

Front

What are crests and troughs in a wave?

Back

Crests are the highest points of a transverse wave, while troughs are the lowest points.
