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.
