Speed of Waves in Different Media

How does a sound wave behave when traveling through a concrete wall?

• The wave speed does not change as it travels through the wall.

• The wave speed will change depending on which side of the wall the wave is coming from.

• The wave slows down as it travels through the wall, and speeds up on the other side.

• The wave speeds up as it travels through the wall, and slows down on the other side.

Which of these occurs FIRST when a wave moves from deep to shallow water?

• Other parts of the wave travel farther.

• The part of the wave that meets the shallow water slows down.

• The wave refracts.

• The wave bends and travels in a straight line.

________________ is a wave changing direction when it speeds up or slows down.

• Transmission

• Reflection

• Absorption

• Refraction

Which of these statements is true of light refraction?

• Light waves always refract in the same direction regardless of the two mediums’ properties.

• The more light waves slow in a new medium, the more they bend.

• Light waves bend and speed up when traveling from air to water.

• Refracted light waves travel in a curved orbit.
