What will occur when the trough of Wave A overlaps the crest 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.

• Henri’s wave has a higher amplitude and more energy.

• Henri’s wave and Geri’s wave have the same amplitude and the same energy.

• Henri’s wave and Geri’s wave have the same amplitude, but Geri’s has more energy.

• Geri’s wave has a higher amplitude and more energy.
