• refraction

• interference

• diffraction

• superposition

Which of the following provides an example of sound waves being reflected?

A ringing bell makes noise inside a glass jar. Then the air is removed from the glass jar using a vacuum pump. When all of the air leaves the jar, the sound of the ringing bell can no longer be heard. Which of the following best explains why the students can no longer hear the bell?

• The air in the jar provides a medium for the sound to travel through.

• The sound in the empty jar is reflected off the inside of the glass sides.

• The sound runs out of energy.

• The sound has no wavelength.

Geologists can learn about rock layers beneath the surface of Earth using sound waves. They use a vibration truck to send sound waves into the ground. A measuring truck has special microphones, called geophones, that pick up sounds. This method for learning about rock layers depends on what characteristic of sound waves?

• Sound waves can travel through and reflect off rock layers.

• Sound waves require energy, such as electricity to generate them.

• Sound waves can travel for an unlimited distance from the source that creates them.

• Sound waves are absorbed by dense solids and reflect off liquids.
