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.
