2 Guitar Strings and Crumbling Bridges Standing Waves and Resonance

3 Wave Interference Waves are “superimposed” like pulses

4 Example #1 D. Both waves reach maximum amplitude at that point!

5 Example #2 Draw a new wave based on the superposition of waves A and B.

6 A View at the Top When viewed from above, a wave source makes circular patterns crest (wave front) trough At this point, two TROUGHS meet to CONSTRUCTIVELY interfere At this point, two CRESTS meet to CONSTRUCTIVELY interfere At this point, a CRESTS and TROUGH meet to DESTRUCTIVELY interfere

7 Standing Waves REFLECTION and INTERFERENCE together result in STANDING WAVES Standing waves contain a pattern of NODES and ANTI-NODES NODE : stationary points – always 180° out of phase ANTI-NODE : maximum displacement – alternate in/out of phase

8 Example #2 FOUR

9 Resonance Resonance occurs when a medium is vibrated NEAR its NATURAL FREQUENCY Constructive interference occurs to an extreme degree causing vibrations with HUGE AMPLITUDE If the vibration has enough ENERGY and the correct FREQUENCY, the medium may be damaged or destroyed!
