Simple Harmonic Motion
12-4: Wave
Interactions
Constructive interference:
when individual displacements on the same side of the equilibrium position are
added together to form the resultant wave. (added)
Destructive Interference:
when individual displacements on the
opposite sides of the equilibrium positions are added together to form the
resultant wave (subtracted)
Reflection: a wave pulse called the incident pulse
reaches a fixes boundary and is reflected back along the medium identically but
inverted.
Standing waves
: a pattern that results when two waves of the same frequency, wavelength, and
amplitude travel in opposite directions and interfere.
Node: a point in the standing wave that always
undergoes complete destructive interference and therefore is stationary.
Antinode: a point in a
standing wave, halfway between the two nodes, at which the largest amplitude
occurs.
