The points that oscillate with maximum amplitude on a stationary wave.

2 of 11

Different stationary wave patterns are possible, depending on...

...the frequency of vibration.

3 of 11

How are stationary waves formed?

They are formed when two identical waves travelling in opposite directions meet and superimpose. This usually happens when one wave is reflected off the other.

4 of 11

At what value is the amplitude when the point on a stationary wave is a node?

Zero.

5 of 11

Explain what is meant by a 'node'.

The points on a stationary wave that do not move.

6 of 11

Explain what is meant by an 'antinode'.

The points of a stationary wave that oscillate with maximum amplitude.

7 of 11

By what fraction of a wavelength are adjacent nodes (or antinodes) separated?

The distance is equal to half a wavelength.

8 of 11

You pluck a guitar sting halfway along its length and it vibrates with an antinode at it's midpoint. What is this known as?

The fundamental mode of vibration of the string.

9 of 11

What is meant by the term 'fundamental frequency'?

The minimum frequency of a standing wave for a given system or arrangement.

Don't you just love physics?

ACCEPT EITHER: 'Yes! It's the best thing ever!' OR 'No. I wish I'd never chosen it.'
