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.
