Choose the correct answer. Sound can travel through (a) gases only (b) solids only (c) liquids only (d) solids, liquids and gases

Answer is option (d) Solid, liquid and gas.


Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore,can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are the farthest apart. In a vacuum sound cannot travel because there is no matter for it to move through. Sound travels as waves, which are vibrating particles. Sound waves are reflected by surfaces. It is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles.
