Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is frequency in the context of waves?

Back

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

Front

What is the wavelength of a wave?

Back

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

Front

What is amplitude in a wave?

Back

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

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and their crests align, resulting in a wave of greater amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and their crests and troughs align, resulting in a wave of lesser amplitude or cancellation.

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 propagation.

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 propagation.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.
