Oscillation-Part 1

Oscillation –movement back and forth at a regular speed

The best way to explain oscillation is by an illustration. Think of a spring with a block of wood attached to one of the ends, then imagine that you squeezed the spring and then release it. As you may guess the spring will expand sending the block of wood in the direction of opposite the way you squeezed the spring. Oscillation –movement back and forth at a regular speed The best way to explain oscillation is by an illustration. Think of a spring with a block of wood attached to one of the ends, then imagine that you squeezed the spring and then release it. As you may guess the spring will expand sending the block of wood in the direction of opposite the way you squeezed the spring.

Once the spring extends fully it will return in the opposite direction. This process repeats until the spring comes to rest. This motion of the spring and the block going back and forth is called oscillation. What makes oscillations so important is the fact that their movement can create waves. The more important question is “ why are waves important?” Because many things occur as waves. A great example of oscillation causing waves is sound. Sound travels through objects as a wave. Generally it is the oscillation of object that produces these waves.

The easiest way to see this phenomenon is to take a cymbal or a gong* from a drum set and whack it. The result, other than irritating everyone around you, will be a loud crash that resonates from the vibration or oscillation of the cymbal. As the cymbal oscillates it creates sound waves, which travel through the air. If you want to see the waves from the oscillation, right after you bang the cymbal, touch the edge of a glass of water to the cymbal. The surface of the water will have waves caused by the oscillation of the cymbal. The sound waves continue until the oscillations stop. This is how most sounds are produced, something oscillating produces sound waves. You name it: speakers, drums, and most every other device that produces sound will have at least some oscillating component in it. m text block.
