Question Statement:

Q3. Sound waves-

Can travel in vacuum

Can travel only in solids

Can travel only in gases.

Can travel both in solid and gaseous medium.

Explanation:

Correct Answer: D

Sound waves need to travel through a medium such as a solid, liquid or gas. The sound waves travel through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed as tightly as solids, and in gases they are very loosely packed. The spacing of the molecules, enable sound to travel much faster through solid than gases, So sound waves can travel in solid, liquid and gaseous medium.
