An organist in a cathedral plays a loud chord and then releases the keys. The sound persists for a few seconds and gradually dies away. Why does it persist? What happens to the sound energy when the sound dies away?
Solution 15DQ Step 1 of 2: The sound waves cannot travel through empty space, it can travel only through the medium. Since it is carried by vibrations in the material or medium like air , water etc. AS the particles in the medium vibrate, energy will be lost in the form of heat, viscous process and for molecular vibration. So, the sound waves amplitude or intensity gets smaller and smaller until it disappears.
