1
Q
Stationary waves are formed by?
A
The interference of two waves, of the same
frequency and amplitude, travelling in opposite directions.
2
Q
. A stationary wave can be
described in terms of
A
Nodes and antinodes
3
Q
What are fixed points of zero amplitude called? Why is this?
A
Nodes (because nothing is moving)
4
Q

A
Anti-nodes
5

A
Anti-node
7
Q
