Waves

1. Many Types of Waves

   • Sound
     • require a medium for transmission
       • I:E Air or metal
         • transfer of kinetic energy
     • harmonics=number of nodes and anti nodes
       • node=area of no displacement
       • antinode= area of maximum displacement
   • Electromagnetic
     • wide spectrum of waves
       • radio waves longest
         • least intense
       • gamma waves shortest
         • most intense
   • Light
     • angle of incidence= angle of refraction

2. transverse

   • peaks and troughs
   • ocean

3. Longitudinal

   • compression and rarefaction
   • slinky
