Wave Interactions

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

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

Light refracts when traveling from air into glass because light 

• travels at the same speed in air and in glass. 
• frequency is greater in air than in glass. 
• frequency is greater in glass than in air. 
• travels slower in glass than in air.
