Wave Parts & Amplitude

Front

What is amplitude in a wave?

Back

Amplitude is the height of a wave from its rest position to its peak.

Front

What does a tall amplitude indicate?

Back

A tall amplitude indicates that the wave has a lot of energy.

Front

What does a short amplitude indicate?

Back

A short amplitude indicates that the wave has less energy.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is wavelength in a wave?

Back

Wavelength is the distance between two consecutive crests or troughs.

Front

How can you identify the amplitude of a wave in a diagram?

Back

The amplitude is measured from the rest position to the crest or trough.

Front

What happens to the amplitude if the energy of the wave increases?

Back

The amplitude increases.

Front

What happens to the amplitude if the energy of the wave decreases?

Back

The amplitude decreases.

Front

Which part of the wave is represented by letter B in a diagram?

Back

Letter B represents the trough.
