Some students were on a tour exploring the inside of a cave. While the students were in the cave, they realized they heard an echo every time that they spoke. Which MOST likely caused the echo to occur?

• the accumulation of the sound waves

• the diffraction of the sound waves

• the refraction of the sound waves

• the reflection of the sound waves

A city wants to build a new concert hall. They want to avoid echoes and background noises. Which design of the walls would be MOST desirable help avoid echoes?

• They should use bumpy walls for all four sides.

• They should use bumpy walls for only one side.

• They should use smooth walls for all four sides.

• They should use smooth walls for only one side.

A single beam of light is shone into a glass containing milky water. Which statement BEST describes why the beam of light bends downward?

• The milk blocks the passage of light through the water.

• The light is moving from air into another medium.

• The force of gravity affects light more when it is in a liquid.

• The farther light is from its source, the slower it moves.

A student observes that a ray of light bends where it passes from glass into water. What BEST explains this phenomenon?

• The properties of a wave change as it travels from one medium into another.

• The energy of a liquid is greater than that of a solid and increases the amount of light in it.

• The mass of a ray of light varies in proportion with the density of its surroundings.

• A wave consumes energy in a solid but produces energy in a liquid.
