Open Ended

Describe what happens when the incident wave meets a fixed boundary.

Open Ended

Describe what happens when an incident wave meets a free-end?

Multiple Choice

What kind of boundary will cause an out-of-phase reflection for a mechanical wave?

• A fixed boundary because the particles are harder to move.

• A fixed boundary because the particles are easier to move.

• A free-end boundary because the particles are easier to move.

• A free-end boundary because the particles are harder to move.

Open Ended

• Reflection

• Refraction

• Reflaction

Multiple Choice

Does diamond cause light to speed up or slow down, as compared to air?

• SPEED UP because diamond has a HIGHER refractive index.

• SPEED UP because diamond has a LOWER refractive index.

• SLOW DOWN because diamond has a HIGHER refractive index.

• SLOW DOWN because diamond has a LOWER refractive index.

Multiple Choice

What causes a mirage?

• Bending of light due to temperature differences in the air.
