| the speed of a wave is its wave length multiplied by what? | frequency |
| the bending of waves due to change in speed is called what? | refraction |
| the bending of waves around the edge of a barrier is known as what | diffraction |
| the interaction between two waves that meet is called | interference |
| waves that combine to make a wave with larger amplitude in a processes called what? | constructive interference |
