Quest/Test Review for Sound Wave Interactions

From your Lesson 2 self-check: #3. This diagram shows what happened after a wave traveling from the left encountered a boundary between its original medium and another, less dense medium. What happened at the boundary between media? Select all that apply.

• Some of the wave’s energy was transmitted to the less dense medium.

• Part of the wave was reflected back into the original medium.

• Particles were carried from one medium to the other.

From your Lesson 2 self-check: #4. Sound is made up of __________ mechanical waves. As a sound wave travels through a medium, it __________ moves particles in that medium. When the sound wave strikes a boundary between air and water, it will generally be _________ reflected.

• transverse, permanently, completely

• longitudinal, temporarily, partially

• transverse, temporarily, completely

• longitudinal, permanently, partially

From your Lesson 2 self-check: #5. This diagram represents a sound wave traveling from left to right. As the wave passes the location of the particle represented by the red dot, how does the particle move?

• The particle travels from left to right along with the sound wave.

• The particle vibrates horizontally, moving both left and right.

• The particle vibrates vertically, moving both up and down.

From your Lesson 2 self-check: #6. As a sound wave spreads through the air, it moves the air particles smaller and smaller distances. What causes this change in the amplitude of the wave? Select all that apply.

• Amplitude decreases as the energy of a wave spreads across a greater amount of the medium.

• Amplitude decreases as the medium’s particles move away from the sound’s source.

• Amplitude decreases as friction transforms energy from the sound wave.

From your Lesson 2 self-check: #A. What happens when a mechanical wave travels through a medium?

• The wave carries particles along with it.

• The wave vibrates particles as it moves through them.

• The wave does not affect the medium’s particles.

From your Lesson 2 self-check: #B. Which statements describe why a wave’s amplitude might decrease as it moves through a medium? Select all that apply.

• The wave loses energy as it moves between media.

• The wave’s amplitude decreases as the wave spreads out.

• The wave’s energy is absorbed by the medium.

From your Lesson 2 self-check: #C. Which statements describe the properties of the transmitted and reflected waves when a mechanical wave meets the boundary between different media? Select all that apply.

• The transmitted wave will have a different speed than the original wave.

• The transmitted wave will have the same speed as the original wave.

• The transmitted wave will have the same amplitude as the original wave.

• The reflected wave will have a different amplitude than the original wave.

• The reflected wave will have the same speed as the original wave.

Which wave in the diagram has the greatest pitch?

• 1

• 2

• 3

• 4

• decibel
• amplitude
• frequency
• rest position
