sound is a form of energy that produces a sensation of hearing in our ears. Sound is produced by a vibrating body. When we strike a pan , or play the guitar vibrations are produced which produce sound. The vibrations that are produced sometimes we can see them , sometimes we cannot . If we throw a stone in a pond we hear a splashing sound and the ripples of the water can be seen , however when a pan is struck the vibrations may not be visible to us. Two important things to remember are-Amplitude and Frequency.
Amplitude-the maximum extent a vibration can go to from its mean position.
Frequency-the number of oscillations by a vibrating body in a second. Unit of frequency is Hertz (Hz).
