Have you ever experienced having a really bad cell phone reception in the middle of an open, urban area?

Question:
What happens when a wave meets another wave?
Wave + Wave = ?

Superposition (Interference)• Two waves can be ‘added’ together
• Constructive interference occurs when the two waves are in phase (i.e. crests meet crests, troughs meet troughs)
• Destructive interference occurs when they are 180 degrees out of phase (i.e. crests meet troughs)

Standing Wave, Nodes and Antinodes• Wave produced by the superposition of
two equal but opposite waves
• Antinodes – places where constructive interferences occur (double crest and double trough)
• Nodes – places where destructive interferences occur (crest + trough = zero displacement)

Interference Pattern• Anti-nodes are formed when constructive
interferences occur where two waves are in phase because the path differences are whole numbers (0, 1, 2, 3…).
• Nodes are formed when destructive interferences occur where two wave are 180o out of phase because the path differences are ½, 1½, 2½, 3½…
