Vertical applications of
SHM
As wave pulses travel,
reflect, travel back,
and repeat the whole
cycle again, waves in
phase will add and
waves out of phase
will cancel.
, Standing Waves On a String
The standing waves in the next figure are
produced by fixing the string at one end and
attaching the other end to a vibrator oscillating
at the appropriate frequency. The harmonic
waves created by the vibrations travel down the
string, are reflected when they reach the fixed
end, and then move back toward the vibrator. If
the string has the appropriate length, the waves
traveling in opposite directions add to produce
standing waves.
, Standing waves on a string
Fixed at both ends, the resonator has waveforms that match.
In this case, the standing waveform must have nodes at both
ends. Differences arise only from increased energy in the
waveform.
