Waves

Waves

1. A wave is a disturbance that travels through space

   • These disturbances are accompanied by the transfer of energy

2. Mechanical waves

   • Require a medium
     • Like air or water

3. Electromagnetic waves

   • Do not require a medium
     • Can travel through a vacuum

4. Tranverse waves

   • Oscillations perpendicular to direction of travel
   • Electromagnetic waves can only be tranverse

5. Longitudinal waves

   • Oscillations parallel to direction of travel
   • Mechanical waves can be longitudinal or tranverse

6. Properties

   • Wavelength
   • Amplitude
   • Frequency
   • Period
