Question

What is the velocity of sound in vacuum?

• A. 332 m $s^{-1}$
• B. 330 m $s^{-1}$
• C. 288 m $s^{-1}$
• D. Zero

Answer 1

The correct option is D Zero

The speed of sound in a vacuum is zero meters per second, as sound cannot travel in a vacuum. The sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air. Since a vacuum is an empty space, there is no medium for the sound to travel through.
