what is mean by soures of sound
Answers
Explanation:
A sound is a form of energy, just like electricity, heat or light. Let’s examine some sources of sounds like a bell. When you strike a bell, it makes a loud ringing noise. Now, instead of just listening to the bell, put your finger on the bell after you have struck it. Can you feel it vibrating? This is the key to the sound. It is even more evident in guitars and drums. You can see the wires vibrating every time you pluck it. When the bell or the guitar stops vibrating, the sound also stops.
The to and fro motion of the body is termed as Vibration. You can see examples of vibrations everywhere. Vibrating objects produce sound. Some vibrations are visible, some aren’t. If you pull and then release a stretched rubber band, the band moves to and fro about the central axis and while doing so it also produces a sound. The sound moves through a medium by alternately contracting and expanding parts of the medium it is travelling through. In physics,
Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
