Which from the following is true for Sound?

A. Sound cannot travel through a vacuum
B. Sound cannot travel through gases
C. Sound cannot travel through liquids
D. Sound cannot travel through solids

Check Answer

The correct answer is: A) Sound cannot travel through a vacuum.

Sound is a type of energy that travels through vibrations in a medium, such as air, water, or a solid. It is produced by the movement or vibration of an object, and is transmitted through the medium as a series of compressions and rarefactions.

Sound cannot travel through a vacuum, because a vacuum is a region of space that is completely empty of matter. There is no medium in a vacuum to transmit the vibrations of sound, so sound waves cannot propagate through it.

Sound can, however, travel through gases, liquids, and solids. The speed of sound depends on the properties of the medium, such as its density and elasticity, and is generally faster in denser and more elastic materials. For example, sound travels faster through water than it does through air, and faster through steel than it does through wood.
