Wave Interactions 11/10 Completed p2 and p6

Reflection Bouncing back of a wave when it meets a surface. When wave medium are free (not attached), they will reflect the wave. If wave medium is attached, it will turn wave upside-down and then reflect.

Diffraction Bending of waves as they pass an object’s edge or opening. Original wave bent

Refraction Bending of waves as they pass from one medium to another. Ex: light traveling through water then air. Light bent when enters water.

Waves travel at same frequency Interference Combo of 2 or more waves that exist in the same place at the same time. Constructive interference: 2 waves combine so that resulting wave is bigger than the orig. waves Waves travel at same frequency

Destructive Interference 2 waves combine so that resulting wave is smaller than the largest of orig. waves. Waves travel at diff. frequencies

Standing Waves A standing wave has both destructive and constructive interfernce. The anti nodes are the location of constructive interference. The nodes are the location of destructive interference.
