Wave Interactions
Physics
Term | Definition |
---|---|
Waves are split into 2 categories, | Strings and Pipes |
String Ends | End and start with NODES |
Pipes have two types, | open pipes and closed pipes |
Open pipes ENDS | Start and end with ANTINODES |
Closed pipes ENDS | Starts with NODE, ends with ANTINODE |
Count Harmonics: Strings | Amount of ANTINODES |
Count Harmonics: Open pipes | Amount of NODES |
Count Harmonics: Closed pipes | Amount of ANTINODES and NODES minus ONE |
Nodes | Where two waves cancel out, resulting in zero amplitude. |
Antinodes | Where two waves overlap, doubling the amplitude. |
Antinodes are examples of | constructive interference |
Nodes are examples of | destructive interference |
PHASE REFLECT: Lower Density to Higher Density | Out of Phase (180) |
PHASE REFLECT: Higher Density to Lower Density | In Phase |
AMPLITUDE: Lower Density to Higher Density | Lower |
AMPLITUDE: Higher Density to Lower Density | Higher |
