Diffraction is the bending of a wave as it mores around an obstacle or passes through a narrow opening.

• True
• False

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
