Behavior of Waves

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

• They are not affected by the interference and maintain their original amplitude throughout the movement.
• They take on and keep a new amplitude based on the result of the interference until the end of the movement.
• They temporarily take on a new amplitude due to the interference but resume their original amplitude until the end of the movement.
• Both waves are always counteracted and cease to exist.

If a medium for a mechanical wave is secured on both sides with one side remaining still and the other producing a continuous wave, which behavior does that wave exhibit?

• Scatters (no pattern - moves in random directions throughout medium)
• Reflects ( bounces back and forth throughout medium)
• Transmits (continues to move through the medium in original direction)
• Ceases to exist - the secured opposite end stops the energy flow of the wave
