	The ~~modes of~~ vibration associated with resonance in ~~extended~~ objects like strings and air columns have characteristic patterns called ~~standing~~ waves. These standing ~~wave modes~~ arise from the combination of reflection and interference such that the reflected waves interfere constructively with the incident waves. An important part of ~~the condition for~~ this constructive interference ~~for stretched strings~~ is the fact that the waves change phase upon reflection from a fixed end. Under these conditions, the medium appears to vibrate in segments or regions and the fact that these vibrations are made up of traveling waves is not apparent - hence the term "standing wave".		The vibration associated with resonance in objects like strings and air columns have characteristic patterns called '''Standing waves'''. These standing waves arise from the combination of reflection and interference such that the reflected waves interfere constructively with the incident waves. An important part of this constructive interference is the fact that the waves change phase upon reflection from a fixed end. Under these conditions, the medium appears to vibrate in segments or regions and the fact that these vibrations are made up of traveling waves is not apparent - hence the term "standing wave".

	The behavior of the waves at the points of minimum and maximum vibrations (nodes and antinodes) contributes to the constructive interference which forms the resonant standing waves. ~~The illustration above involves the~~ transverse waves ~~on a string~~, but ~~standing waves~~ also occur with the longitudinal waves in an air column. Standing waves in air columns also form nodes and antinodes, but the phase changes involved must be separately examined for ~~the case of~~ air columns.

 This describes a wave that oscillates in time, but has a spatial dependence that is stationary: sin(''kx'').  At locations ''x''&nbsp;=&nbsp;0, ''λ''/2, ''λ'', 3''λ''/2, ...
