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.

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

· Why can we hear around a corner but not see?

• Increased amplitude of the light wave means brighter light

• the smaller the opening the more diffraction, light waves are so small you will have little diffraction.

• Decreased amplitude of the light wave means dimmer light

Give an example of Diffraction.

• Water droplets act as prisms to separate white light into the ROYGBIV spectrum

• Decreased amplitude of the sound wave means softer sound

• the smaller the opening the more diffraction, light waves are so small you will have little diffraction.

• hearing the bass of the music through the openings in a car (longer wavelengths)
