Question

Sound travels the fastest through vacuum. State whether true or false.

• A. True
• B. False

Answer 1

The correct option is B False

Sound waves cannot travel through a vacuum. They need a physical medium to travel through. This is because they propagate mechanically by moving material particles. A vacuum is defined as space that contains no matter. So it does not contain any particle using which the sound energy can travel. Hence the given statement is false.
