• node

• destructive interference

• antinode

When a crest and crest or trough and trough of two different waves interact you _________ the amplitudes.

• add

• subtract

• multiply

• divide

What is the process called when a crest interferes with a trough to lessen or cancel the amplitude of a wave.

• Constructive interference

• Destructive interference

The combination of two or more waves that result in a single wave

•  diffraction

•  resonance

•  reflection

•  interference

Use the picture to answer the question.

In this picture, Wave A and Wave B will create—

• Resonance

• Destructive (negative) interference

• A higher pitch

• A lower pitch

Use the picture to answer the question. What will happen if Wave A and Wave B overlap? Choose 3 correct answers.

• The total amplitude will double.

• Negative interference will occur.

• There will be no sound.

• A new wave pattern will occur.

• 1. There will be resonance between the two waves.

​ Wave Interference occurs when two or more waves ​ (a)   and form a new wave.

When the wave is built up that is called ​ (b)   interference, when the wave gets ​ (c)   that is called ​ (d)   interference.

• overlap

• constructive

• destructive

• smaller

What will happen when these two waves interact?

• the waves will interfere constructively to produce a larger wave

• the waves will reflect off each other and move in the opposite direction

• the waves will collide with each other and cancel each other out

• the waves will interfere destructively to produce a smaller wave

Which explains why when the waves pass each other part of the rope does not move?

• the waves interfere destructively and cancel each other out

• the waves interfered constructively and produced a trough

• the waves reflected off each other and went in the othe direction

• the waves absorbed the energy from each other and cancelled out
