1. Superposition
Superposition is the ability of waves to superimpose (add displacements & energy) as they move through each other.
Constructive interference.
Approaching
Overlapping
Receding

2. Destructive interference .
Approaching
Overlapping
Receding

3. Combining waves of the same f
What happens when two waves are present at the same place at the same time?

4. The Principle of Interference / Superpositioning
For waves:
The resulting wave = the sum of the individual waves
Constructively
Destructive
This applies to all waves: water, light, sound, etc.

5. Interference: What happens when two waves pass through the same region?
When two crests overlap it is called constructive interference. The resultant displacement is larger then the individual ones.
When a crest and a trough interfere, it is called destructive interference. The resultant displacement is smaller.
