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.

What is the definition of Diffraction?

• The bending of waves as they enter a new medium

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

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

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

Which of the following represents refraction?

• A

Refraction occurs when _____________

• the wave's speed changes by entering a new medium
• a wave bounces off of a boundary
• waves parts meet each other
• waves bend around a barrier

When a sound wave experiences reflection, we hear

• a louder sound
• an echo
• a quieter sound
• nothing
