Waves

Which statement best explains the results of the investigation for wave 2?

• The wave traveled faster in the denser media because the particles in the media are closer together.

• The wave traveled slower in the denser media because the particles in the media are closer together.

• The wave traveled faster in the denser media because the particles in the media are farther apart.

• The wave traveled slower in the denser media because the particles in the media are farther apart.

Which statement BEST describes how changing the energy of a wave affects its amplitude and loudness?

• Decreasing the wave's energy causes the loudness to decrease and the amplitude to increase.

• Decreasing the wave's energy causes the loudness to decrease and the amplitude to decrease.

• Increasing the wave's energy causes the loudness to increase but the amplitude to remain the same.

• Increasing the wave's energy causes the loudness to decrease but the amplitude to remain the same.

A musician wants to build a sound studio in his home but is concerned about disturbing his family. He also does not want to cause the sound inside the room to have echoes, which occurs when the sound waves bounce back after hitting the walls. He decides to line the walls of his studio with a material called polyurethane foam. Why did the musician decide to use polyurethane foam to line the walls of the sound studio?

• The foam absorbs the sound waves without reflecting them back into the room.

• The foam reduces the amount of reflection by allowing the sound to transmit through the walls.

• The foam allows the sound waves to transmit through the walls without reflecting back into the room.

• The foam reflects the sound waves into the room and prevents them from transmitting through the walls.
