Quiz on Waves and Their Properties

What is the fundamental idea behind waves?

• Energy moves through individual particles.

• Waves require a vacuum to propagate.

• A perturbation in one place causes a perturbation in a neighboring area.

• Waves are static and do not move.

What is constructive interference?

• The cancelation of one wave by another.

• The spreading out of a wave as it moves past an edge.

• The combining of two waves to yield a greater amplitude.

• The change in heading of a wave front.

What is a crest in a wave?

• The distance between consecutive crests.

• A point on a wave with a maximum upward displacement.

• A place in a wave pattern where the amplitude is at its equilibrium value.

• A point on a wave with a maximum downward displacement.

What does Huygens’ Principle explain?

• The superposition of two or more waves.

• The change in heading of a wave front.

• Diffraction and refraction.

• The distance between consecutive troughs.

What is the law of superposition?

• Waves can be combined and decomposed using arithmetic.

• Waves spread out as they move past an edge.

• Waves change direction when entering a new medium.

• Waves require a medium to propagate.

What is a node in a wave pattern?

• The distance between consecutive crests.

• A place where the amplitude is at its equilibrium value.

• A point on a wave with maximum downward displacement.

• A point on a wave with maximum upward displacement.
