Basic Wave Properties

Front

What is the definition of a wave?

Back

A wave is a repeating disturbance or vibration that transfers or moves energy from place to place.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

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.

Front

What is frequency?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum distance that the points of a wave move from their rest position.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves vibrate perpendicular to the direction of energy transfer, while longitudinal waves vibrate parallel to the direction of energy transfer.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves.

Front

What is an example of a longitudinal wave?

Back

An example of a longitudinal wave is a sound wave.

Front

How does energy transfer in a wave?

Back

Energy is transferred through the medium as the wave propagates, causing particles in the medium to oscillate.
