- 1What behaviors do all waves have in common?The behaviors all waves have in common are reflection, refraction, and diffraction.
- 2How would you define reflection?Reflection is the bouncing back of waves after they hit a surface they cannot pass through.
- 3Describe what happens when waves diffract.When waves diffract, there is a surface with a gap in it, and when a wave passes through it it spreads out in all directions.
- 4Summarize in your own words what happens during interferance?In interference, if the waves align exactly crest to crest, and trough to trough, then the amplitude and energy increases, but if they do not align exactly they will subtract each amplitude with another waves amplitude. In some places the amplitude will increase, and in some places it will subtract.
- 5Explain what happens when waves encounter a medium they cannot travel through.They reflect, because they bounce off the surface they cannot pass through.
- 6Describe a situation in which waves would diffract.If a tv is on in a room and the door is open, in the other room, the sound waves will spread out in all directions.
- 7Describe two ways that waves are affected by interference.?
- 8Explain how reflection and diffraction can happen at the same time in a wave.If there is a surface, and waves are coming toward the surface, and there is a gap in it, the waves will bounce off the surface and some will go through the gap and spread out in all directions.
