Waves

Waves

1. Electromagnetic

   • No Medium
   • Speed of Light

2. Mechanical

   • Requires Medium

3. Phase

   • In-Phase
     • Travelling in same direction
   • Anti-Phase
     • Opposite Direction

4. Node

   • No Vibrations
   • Superpose
   • Anti-phase

5. Fundamental Frequency

   • Number of Anti-Nodes

6. Amplitude

   • Max Displacement (equilibrium)

7. Anti-Node

   • In-Phase
   • Constructive

8. Superposition

   • Two waves added together
     • Constructive
       • Waves are in-phase
     • De-constructive
       • Anti-phase
       • Zero-Amplitude

9. Velocity

   • f*λ
