Waves Interactions

Constructive interference will cause the wave to 

• Increase its displacement
• Decrease its displacement 
• Make its displacement stay the same

Destructive interference is 

• When the two waves affect  each other in a negative way 
• The two waves add together and produce a single wave of greater amplitude
• Are in phase 

What is interference?  

• occurs when two or more waves overlap and combine 
• occurs when two or more waves combine and neutralize each other 
• when one waves travels alone

Which wave behavior do noise cancelling headphones use?

• diffraction
• refraction
• constructive interference
• destructive interference

In a standing wave, destructive interference creates points of zero amplitude called nodes. Which letters represent this.

• A,E,F
• B,D,F
• B,C,D
• A,C,F
