1. SOUND AND LIGHT Chapter 1 THE ENERGY OF WAVES

2. Section 3 Wave Interactions

3. reflection the bouncing back of a wave after it strikes a barrier or object

4. reflected sound wave echo

5. the bending of a wave as it passes at an angle from one medium to another refraction

6. the bending of waves around a barrier or through an opening diffraction

7. a wave interaction that occurs when two or more waves overlap and occupy the same space at the same time interference

8. when the crests and troughs of two waves overlap resulting in a wave with higher crests and deeper troughs than the original waves constructive interference

9. when the crests of one wave and the troughs of another wave overlap, resulting in a smaller amplitude than the original waves destructive interference

10. when two waves with the same amplitude combine by destructive interference and cancel each other out total destructive interference Total

11. a wave that forms a stationary pattern in which portions of the wave are at rest position due to total destructive interference and other portions have a large amplitude due to constructive interference standing wave

12. frequency at which standing waves are produced resonant frequency Tacoma Narrows Bridge

13. Using Resonant Frequency

14. what occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate resonance

15. a wave in which the particles vibrate with an up-and-down motion, perpendicular to the direction in which the wave is traveling transverse wave

16. wave in which the particles move back and forth along the path that the wave travels longitudinal wave
