waves

waves

1. sound

   • required particles
     • sound waves required particles to travel through sound. cannot travel through space because there are no air particles
     • sound will travel faster and further if particles are closer together so sound travels a way longer way in air then water
   • longitudinal waves
     • longitudinal waves are compression waves. air particles move closer and further apart

2. electromagnetic spectrum

3. light

   • transverse waves
     • transverse waves are electromagnetic waves that can travel through space a clear line of sight is required for light waves to be visible(they are blocked by opaque objects)
