After reading this section you will be able to do the following:. You are in a long mining tunnel deep under the earth. 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? The speed of sound is not always the same.

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.

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly. And gases are very loosely packed.
