Wave Parts & Amplitude

Front

What is amplitude in waves?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What does a tall amplitude indicate about a wave?

Back

A tall amplitude indicates that the wave has a large amount of energy and the peaks are higher.

Front

What does a short amplitude indicate about a wave?

Back

A short amplitude indicates that the wave has less energy and the peaks are lower.

Front

How can you visually identify tall amplitude in a wave?

Back

You can identify tall amplitude by looking for high peaks and deep troughs in the wave.

Front

How can you visually identify short amplitude in a wave?

Back

You can identify short amplitude by looking for shorter peaks and shallower troughs in the wave.

Front

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

Back

If the amplitude increases, the energy of the wave also increases.

Front

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

Back

If the amplitude decreases, the energy of the wave also decreases.

Front

Can amplitude be measured? If so, how?

Back

Yes, amplitude can be measured by calculating the distance from the rest position to the crest or trough of the wave.

Front

What is the relationship between amplitude and sound volume?

Back

In sound waves, a larger amplitude means a louder sound, while a smaller amplitude means a softer sound.

Front

What is the relationship between amplitude and light brightness?

Back

In light waves, a larger amplitude means a brighter light, while a smaller amplitude means a dimmer light.
