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 does reflection include(s)?

• angle of incidence

• angle of reflection

• angle of bounce

• angle of reflecting

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.

Rainbows are made by...

• water

• rain

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

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

What is the definition of Constructive Interference?

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

• 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.

[Constructive Interference] How does this affect a sound wave? A light wave?

• Decreased amplitude of the light wave means dimmer light

• Increased amplitude of the sound wave means louder sound

• Increased amplitude of the light wave means brighter light

• Decreased amplitude of the sound wave means softer sound

What is the definition of Destructive Interference?

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

• The bending of waves as they enter a new medium

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