Wave Interactions

Constructive interference will cause the wave to 

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

A standing wave appears to be staying in one place.

• True
• False

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 

Constructive interference is

• When two waves affect one another in  a positive way.
• Produce a single wave of greater amplitude (add together)
• Both

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 in the diagram has the greatest wavelength?

• 1
• 2
• 3
• 4
