What is a medium?

• something between a small and a large?
• the substance through which a wave can travel
• a pattern of vibration that simulates when a wave is standing still
• the distance from any point on a wave to an identical point on the next wave

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

Match the following

• Interference

• Wave stays in the same medium but bends around an obstacle.

• Diffraction

• Wave encounters a barrier that causes the wave to return.

• Transmission

• Wave changes direction when moving from one medium to another

• Reflection

• Waves combine together to form a larger wave.

• Refraction

• Wave completely passes through a medium.
