Stationary Waves Flashcards
1
Q
What are the conditions for stationary waves to form?
A
- need to be travelling in opposite directions
- have the same frequency
- approximately equal amplitudes
2
Q
What is a node?
A
Points on a stationary wave at which there is no displacement in the particles at any time
3
Q
What is an anti node?
A
The displacement of the particles in a stationary wave varies by the maximum amount.
4
Q
What is a stationary wave?
A
Stationary waves are produced by interference in accordance with the principle of superposition.
5
Q
What is superposition?
A
The resultant displacement of two or more waves is equal to the vector sum of the waves displacements at that point.
6
Q
What is the distance between 2 separate adjacent nodes?
A
Wavelength/2
7
Q
What is the distance between a node and a anti node?
A
Wavelength/4
