The higher the temperature of the medium the faster the speed of the sound wave. Maybe you can hear the train coming or a car rolling by from 3 blocks away. Have you ever noticed that in the summer time you can hear sounds from farther away. Temperature of the medium also plays a great deal in the speed of sound. The molecules in a gas are far apart so it takes longer for the compressional wave to move the matter. Conversely, sound travels slowest through gasses. The molecules in a solid are closer together so the compressional wave can move very quickly. Sound travels the fastest through soilds. A medium is the matter through which a wave travels such as a solid, liquid or gas. Sound travels at different speeds through different mediums. ![]() Their voices are traveling through the air to your ears. But how does sound itself travel? Your friends call to you. Since sound is a form of energy, it can make things move. Try experiment #1 to see exactly how sound travels through solid objects. Sound can not travel in a vacuum or through empty space. Sound travels through solids liquids and gasses only. ![]() A sound wave travels as a longitudinal wave through some type of medium. Think about a guitar string when it is plucked.
