Wave Nature

1. Imaging and Signalling

   • Medical imaging
   • Communications
   • Scientific imaging
   • Seeing
   • Infrared cameras

2. Transferring Energy

   • Carries energy but not material
   • EM waves heat stuff up
   • X-Rays and Gamma rays cause ionisation
   • Sounds cause vibrations
   • Wave power can generate electricity
   • Wave source loses energy

3. Wave Properties

   • Reflection
     • Wave bounces back when it hits a boundary
   • Refraction
     • Wave changes direction as it enters a new medium
   • Diffraction
     • Waves spread out as they go through a gap
