Q.

These waves cannot be trans-mitted through vacuum –

A. Light
B. Sound
C. Heat
D. Electromagnetic
Answer» B. Sound
Explanation: Sound is a mechanical wave that is created by vibrating objects and propagated through a medium from one location to another. Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles. That is, mechanical waves cannot travel through a vacuum.
