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 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

• It was released into the air.

• It was bent and changed direction.

• It was absorbed by the surface.

• It was scattered by the surface.

A student placed a pencil in a cup of water. The pencil appears broken because light

• always travels in a straight line.

• refracts because it bends when it passes through water.

• diffracts because it bends when it passes through water.

• reflects because it bends when it passes through water.
