	Wave patterns occur in specific manners based on the certain frequency applied. The frequencies of the wave and their relative patterns are called harmonics. Harmonics behave in a way that provides a convenient mathematical model based on the wavelength of the wave, the harmonic type, and the length of the medium it is propagating through. ~~[[File:1Harmonics.jpg\|thumb\| First (Fundamental), second, third, fourth, and fifth Harmonics.]]~~ The first harmonic consists of a single antinode in the middle of the medium, and this antinode oscillates up and down continuously. Next, the second harmonic creates two antinodes and three nodes. A full wavelength can be observed here. The third harmonic consists of three antinodes and four nodes. From these progressive patterns, a mathematical relationship can be derived to calculate the length of medium based on the wavelength of the wave. This relationship can be seen below.

	==Connectedness==		==Connectedness==
			#This concept connects to a wide variety of scientific studies. For example, when discussing and building motors in cars, one can observe resonance when traveling at a specific speed because the motor will vibrate at a specific frequency that causes components of the car to quiver if connected to the motor. Mechanical resonance can be induced in an object by humans to destroy that object. This concept connects to music as discussed above. Finally, there is also electrical resonance as seen when tuning radios. Tuning a radio means adjusting the circuit's resonance frequency to that of the desired radio wave.
			#The concept of resonance applies to mechanical engineering because when designing a system or structure, the resonant frequency of said object must be taken into account. If this is not done, the system could fail or be destroyed if it encounters its resonant frequency induced by another part of the system.
			#An interesting application of resonance is in the use of MRI (magnetic resonance imaging) technology. An MRI produces an oscillating magnetic field that is applied to the patient at the correct resonant frequency of the protons in the body. Then, the excited protons emit radio waves that are picked up and recorded by coils in the machine. Based on the different waves recorded by the coils, the MRI machine can pinpoint and map out parts of the interior of the human body. This is all possible because the field vibrates the protons at a resonant frequency.

	Tuning forks have a stable, consistent pitch when struck, and they have been used to tune instruments since the 17th century. ~~[[File:Tuning.jpg\|thumb\|left\|This is a tuning fork.]]~~ These tools make use of resonance because then struck on a surface, the tines (the prongs of the fork) vibrate at the same frequency in opposite directions to produce a tone. Since the tines move in opposite directions, the vibrations it creates interfere, making a standing wave unique to each individual tuning fork. With this, a musician can match a note on his or her respective instrument to the tone produced by the fork and tune their instrument from there.
