Constructive interference happens when two waves are:

• out of phase.

• zero amplitude.

• in phase.

The F-18 Growler carries electronic warefare equipement to disable enemy radar systems. How does it do this?

• It cloaks the radar waves

• It jams the radar signal with intense waves

• It reflects the radar away

• It destroys the radar signal

When 2 waves temporarily interfere with each other then resume their course of movement, which of the following is true?

• They take on and keep a new amplitude based on the result of the interference until the end of the movement.

• They are not affected by the interference and maintain their original amplitude throughout the movement.

• Both waves are always counteracted and cease to exist.

• They temporarily take on a new amplitude due to the interference but resume their original amplitude until the end of the movement.

When 2 waves meet and create a bigger wave

• Constructive Interference

• Destructive Interference
