Q:

Sound travels fastest in

A) Vacuum B) Air
C) Glass D) Water

Answer:   C) Glass



Explanation:

Sound is a mechanical vibration and needs a medium for propagation. The higher the density of the medium, the faster the sound travels. So, sound cannot travel through vacuum.

 

As the sound travels faster in solids than liquids and gases, sound travels faster in the glass than Air and water.
