Sound


   
 
Sound as a Wave
A ringing bell, a thunderclap, laughter, and rock music are sounds that seem very different to us. However, all sounds are alike because they are waves. Let us understand how wave properties can be applied to sound.
 
Sound is the form of energy propagated as waves which our ears receive. When we speak, our vocal cords vibrate. When we play a guitar, the spring on it makes to and fro motion and produces sound. A tuning fork also produces sound due to its vibrations. So, a body produces sound by virtue of its vibrations. Sound waves cannot travel through vacuum, i.e., they need a material medium to travel.
 
You can hear because, when sound waves reach your ears, the waves make your eardrums vibrate. Nerves then send to your brain the messages about the vibrations. The brain interprets the messages as sound.
