Describe particle movement and wave movement in a transverse wave.

• Particles move parallel to wave direction; wave moves perpendicular

• Particles move perpendicular to wave direction; wave moves parallel

• Particles move in circular motion; wave moves in a straight line

• Particles move randomly; wave moves in a zigzag pattern

Describe particle movement and wave movement in a longitudinal wave.

• Particles move perpendicular to wave direction; wave moves parallel

• Particles move in circular motion; wave moves in a straight line

• Particles move parallel to wave direction; wave moves parallel

• Particles move randomly; wave moves in a zigzag pattern

Describe particle movement and wave movement in a surface wave.

• Particles move in circular motion; wave moves in a straight line

• Particles move parallel to wave direction; wave moves parallel

The Doppler Effect is a change in wave frequency due to motion. Which of the following is an example?

• Change in wave speed due to medium change; e.g., sound in air vs. water

• Change in wave frequency due to motion; e.g., ambulance siren passing by

• Change in wave amplitude due to distance; e.g., music volume decreasing

• Change in wave direction due to reflection; e.g., echo in a canyon
