Constructive and Destructive Interference

In a standing wave, constructive interference creates larger amplitudes.  The points of maximum amplitude are antinodes.  The letters for these are?

• B,C,D

• A,E,F

• A,C,F

• B,D,E

What type of waves are produced whenever two waves of identical frequency interfere with one another while traveling in opposite directions along the same medium?

• Standing

• Constructive

• Destructive

• Transversal

the interaction among two or more waves in which displacements combine to produce a wave with a larger displacement

• Doppler effect

• Constructive interference

• Destructive interference

• Intensity

the interaction among two or more waves in which displacements combine to produce a wave with a smaller displacement

• Doppler effect

• Constructive interference

• Destructive interference

• Sonar

the interaction of two or more waves the combine in a region of overlap

• reflection

• refraction

• diffraction

• interference

a point on a standing wave that has no displacement from the rest position

• node

• antinode

• Sonar

• Diffraction

What will occur when the trough of Wave A overlaps the trough of Wave B?

• Destructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

• Constructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

• Destructive interference will occur, causing the new wave to have less energy than Wave A or Wave B.

• Constructive interference will occur, causing the new wave to have less energy than Wave A or Wave B.

Pierce conducts an experiment in which waves collide in a way that the energy increases. What has occurred?

• refraction

• reflection

• constructive interference

• destructive interference

The waves created by two speed boats in a lake interact to form larger waves. This is an example of

• constructive interference.

• destructive interference.

• absorption
