When sound travels and when it doesn’t

What determines the speed of sound through matter?. When sound travels and when it doesn’t. Sound waves travel much more slowly than light waves do. The speed of sound varies with the material through which it moves. Think about our table tapping experiment…. At the speed of sound.

  1. What determines the speed of sound through matter? When sound travels and when it doesn’t

  2. Sound waves travel much more slowly than light waves do. The speed of sound varies with the material through which it moves. Think about our table tapping experiment…. At the speed of sound

  3. The reason you were able to hear the tapping so much better when your ear was placed on the table than when it was not is because less sound energy was changed into other forms of energy in the wood as opposed to the air. But why? At the speed of sound

  4. Take a look at the examples below. Because wood’s particles are so much more closely packed together, they are able to transmit the sound much quicker than the particles in air which are less packed. The closer together the particles are the better sound is transmitted. At the speed of sound

  5. The speed of sound also varies with the temperature of materials which sound passes through Particles of matter move faster at higher temperatures than lower temperatures. As the temperature rises, particles take less time to collide with one another. As a result, they pass along the wave energy more quickly AT THE SPEED OF SOUND

  6. Unlike light waves, sound waves can travel ONLY where there is matter to carry them. Sound haves cannot travel through a vacuum. Matter is a must
