Harmonics

by: Emily Bergen

Harmonics- the frequencies of waves and their patterns

The first harmonic motion is where there is no displacement on the ends and then major displacement in the middle. 

The second harmonics motion is when the wave is where two nodes are at the ends and a third node is in the middle.



The third harmonic motion is when happens when the vibrations increase and there are third nodes and two antinodes. 

Harmonics are the frequencies at which a system experiences resonance. The first harmonic is the lowest resonant frequency and is often called the fundamental resonant frequency. For a stretched string, it occurs at a frequency where the wavelength of the wave is equal to twice the length of string. The second harmonic occurs at frequency equal to twice the fundamental, the third harmonic at three times the fundamental, etc.
