How can stationary waves be created
Formed when 2 progressive waves with equal frequency and wavelength move in opposite directions interfere with each other
What is a node
A point on a stationary wave with no amplitude
What is an antinode
A point on a stationary wave with maximum amplitude
What frequency do stationary waves occur
Resonant frequencies
What causes resonant frequencies
When the distance between 2 fixed ends of a wave is an interference of multiple half wavelengths
What are characteristics of the first harmonic (the fundamental)
2 nodes and 1 antinode
What are characteristics of the second harmonic
3 nodes and 2 antinodes
What are characteristics of the third harmonic
4 nodes and 3 antinodes
