Parts of a Wave

Front

What is a trough in a wave?

Back

The trough is the lowest point of a wave, where the wave dips down.

Front

What does wavelength represent in a wave?

Back

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

Front

How do you identify the wave with the greatest wavelength in a diagram?

Back

The wave with the greatest wavelength will have the longest distance between consecutive crests or troughs.

Front

What is frequency in the context of waves?

Back

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

Front

How do you determine which wave has the greatest frequency in a diagram?

Back

The wave with the greatest frequency will have the most crests or troughs passing a point in a given time.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases, and vice versa.

Front

What is a crest in a wave?

Back

The crest is the highest point of a wave, where the wave peaks.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the wave's energy.

Front

How can you visually identify amplitude in a wave diagram?

Back

Amplitude can be identified as the vertical distance from the rest position to the crest or trough.

Front

What is the formula for calculating wave speed?

Back

Wave speed = Wavelength × Frequency.
