A Level Physics Harmonics

Simple harmonic motion s h m a level physics simple harmonic motion s h m it a special type of periodic motion in which the acceleration of the body along the path of the body is directed towards a fixed point in the line of motion and is proportional to the displacement of the body from the fixed point. The next highest frequency above the fundamental is called the 1st overtone.

Examples include masses on springs and pendula which bounce back and forth repeatedly.

A level physics harmonics. Successive frequencies where standing waves are produced are called the 2nd harmonic the 3rd harmonic and so on. For the first harmonic the wavelength of the wave pattern would be two times the length of the string see table above. The fundamental frequency is called the 1st harmonic.

Similarly the higher frequencies above the fundamental are termed overtones. A level physics advancing physics simple harmonic motion a level physics advancing physics simple harmonic motion occurs when the force on an object is proportional and in the opposite direction to the displacement of the object. Consider an 80 cm long guitar string that has a fundamental frequency 1st harmonic of 400 hz.

Determining the harmonic frequencies. Thus the wavelength is 160 cm or 1 60 m the speed of the standing wave can now be determined from the wavelength and the frequency.
