Sep 10, Introduction: Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these.

You have a friend that is several thousands of feet away from you in the tunnel. You tell this person using a walkie talkie to yell and clang on the pipes on the tunnel floor at the same time. Press the play button below to find out what happens. What happens when there is a change in the material through which the sound travels?

Sound travels about 4 times faster and farther in water than it does in air. Sound waves travels through a medium such as a solid, liquid, or gas.

Chidren will experience sounds travelling through things in different states: a bag of air, a bag of water, a wooden block. Will a pencil tap heard through a bag of air sound different than a pencil tap heard through a bag of water? Will these taps sound different than a tap heard through a wooden block? Not an Education.

Sound waves are longitudinal waves, they propagate though space from particles colliding with each other. Gases are less dense than liquids or solids, so when sound moves through them, the gas molecules bump into each other less frequently because they are more spread out. This causes the velocity of the sound wave to normally be small, audible to our ears. In liquids, the speed of sound is faster because the molecules are more closely compacted, so the wave can propagate faster. Think of it as like a metal mosh pit. In a heavy metal gig, there are a lot of people we're going to think of them as particles closely compacted exerting repulsive forces on each other. When the moshers push against each other, the velocities of the waves of them pushing each other get faster, because they are closer together.

The Speed of Sound:. Sound travels at different speeds depending on what it is traveling through. Of the three mediums gas, liquid, and solid sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound. Gases: The speed of sound depends upon the properties of the medium it is passing through. When we look at the properties of a gas, we see that only when molecules collide with each other can the condensations and rarefactions of a sound wave move about.
