1 Chapter 1 Interactions of waves

2 Key Terms Reflection Refraction Interference Constructive interference Standing wave Antinode Law of reflection Diffraction Node Resonance

3 Reflection The bouncing back of an object or a wave when it hits a surface through which it cannot pass

4 Refraction The bending of waves as they enter a new medium at an angle.

5 Interference The interaction between waves that meet.

6 Constructive Interference The interference that occurs when waves combine to make a wave with a larger amplitude.

7 Destructive Wave The interference that occurs when two waves combine to make a wave with a smaller amplitude.

8 Antinode A point of maximum amplitude on a standing wave.

9 Law of Reflection The rule that the angle of reflection equals the angle of incidence.

10 Diffraction The bending of waves as they move around a barrier or pass through an opening.

11 Node A point of zero amplitude on a standing wave.

12 Resonance The increase in the amplitude of a vibration that occurs when external vibrations match an objects natural frequency.
