Wave Interactions

Describe diffraction.

• Diffraction is the bending of waves around obstacles and openings.

• Diffraction is the reflection of waves from surfaces.

• Diffraction is the absorption of waves by materials.

• Diffraction is the transmission of waves through a medium.

Distinguish between constructive and destructive interference.

• Constructive interference occurs when two waves combine to form a larger wave, while destructive interference occurs when two waves combine to cancel each other out.

• Constructive interference occurs when two waves cancel each other out, while destructive interference occurs when two waves combine to form a larger wave.

• Constructive interference and destructive interference both occur when two waves combine to form a larger wave.

• Constructive interference and destructive interference both occur when two waves cancel each other out.

Explain how standing waves are produced.

• Standing waves are produced by the interference of two waves traveling in opposite directions.

• Standing waves are produced by a single wave reflecting off a surface.

• Standing waves are produced by the superposition of multiple waves traveling in the same direction.

• Standing waves are produced by the absorption of waves by a medium.

Refraction is the bending of light as it passes from one medium to another.

Interference is a phenomenon where two waves superpose to form a resultant wave of greater, lower, or the same amplitude.

• True

• False

What is the definition of refraction?

• The bending of a wave path as it enters a new medium obliquely.

• The reflection of light from a surface.

• The spreading of waves around obstacles.

• The change in frequency of a wave as its source moves.
