You and your father inspect an empty house with the hopes of buying it. You walk through the rooms talking to one another, and you notice that your voices and footsteps are echoing in the big, empty house. What causes the echo?

• sound waves reflecting off smooth, flat surfaces throughout the house
• sound waves moving around the large rooms
• sound waves moving slowly through air
• sound waves refracting around corners in the empty rooms

Due to the Doppler Effect, when a noise is moving towards an observer, the closer it comes...

• the lower the pitch

• the longer the noise

• the higher the pitch

• the quieter the noise

Due to the Doppler Effect when a noise if moving away from an observer...

• the pitch is lower

• the pitch is higher

• the noise is smoother

• the energy is lower

In the diagram, which letter represents the angle of incidence?

• A

• B

• C

• D
