Wave behavior

What is the definition reflection?

• The bending of waves as they enter a new medium

• Bouncing back of waves from a surface that it can’t pass through

• The bending of waves as they pass through openings or around corners

• When two interfering waves have a displacement in the same direction, two crests and two troughs overlap. Increased amplitude.

What is the definition of Refraction?

• The bending of waves as they enter a new medium

• When two interfering waves have a displacement in the opposite direction, crest and trough overlap. Zero amplitude.

• When two interfering waves have a displacement in the same direction, two crests and two troughs overlap. Increased amplitude.
