Reflection
• Occurs when a wave “bounces” off a barrier
• Examples– Echoes– Light reflection (Moon)

Refraction
• The bending of a wave as it passes at an angle from one medium to another.
• Example – looking into water.

Interference
• Two waves can occupy the same space
• The overlapping of two + more waves
• Constructive Interference increases amplitude
• Destructive Interference decreases amplitude

Constructive Interference
When the amplitude of two waves is in the same direction, the resultant wave is the addition of each waves amplitude.
This is called constructive interference.

Destructive Interference
When the amplitude of two waves is in the opposite direction, the resultant wave is the difference of each waves amplitude.
This is called destructive interference.
When resultant wave has zero amplitude, it is called complete destructive
interference
