1. STANDING WAVES

2. Standing Waves - appear to be ‘standing’ still in their left to right motion - in constant position

3. Standing Waves can occur when a wave interferes with it’s reflected self Check it out!

4. You need to Node this…..

5. There are two main parts of the standing wave

6. You need to Node this….. There are two main parts of the standing wave Node points of complete destructive interference do not move

7. You need to Node this….. There are two main parts of the standing wave Node points of complete destructive interference do not move

8. You need to Node this….. There are two main parts of the standing wave Antinode

9. You need to Node this….. There are two main parts of the standing wave Antinode Points of complete constructive interference Largest amplitude points of the standing wave

10. Harmonics On a musical instrument, the strings are fixed at both ends

11. Harmonics On a musical instrument, the strings are fixed at both ends

12. Harmonics On a musical instrument, the strings are fixed at both ends This means that there must be nodes at each end, and this limits the possible vibrations (or oscillations) of the string

14. In each one of these standing waves, the wavelengths produce a frequency that are known as harmonics. The first standing wave has what is known as the fundamental frequency f. The second standing wave has the second harmonic 2f. The third standing wave has the third harmonic 3f.
