Physics: Resonance and standing waves
standing wave
a wave that is confined to a small space in the medium. It is actually just several traveling waves that are confined to a small space
first harmonic or fundamental frequency
lowest frequency that causes a standing wave. 2 nodes and one anti-node
traveling wave
moves through a medium and isn't confined to a certain space
constructive interference
occurs at the anti nodes of a wave
deconstructive interference
occurs at the nodes of a wave
nodes
part of the wave that looks as if it isn't moving. This includes the end of the wave or string
second harmonic
second lowest frequency that causes a standing wave. 3 nodes and four anti nodes
higher order harmonics
the 4th, 5th, 6th ect. harmonics
anti-nodes
the actual wave looking part of the wave
Harmonics
the frequency and standing wave pairs are known as what
