Properties of Waves PS 4-1

Front

What is the definition of wavelength?

Back

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

Front

What does amplitude represent in a wave?

Back

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

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave.

Front

What is the formula to calculate wave speed?

Back

Wave speed = frequency x wavelength.

Front

What is frequency in the context of waves?

Back

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

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

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 the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa, when wave speed is constant.
