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

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.

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.
