Lesson 2- mechanical wave interaction

Matter that carries sound waves is called a _________

• low
• high
• medium
• surface

Sound travels faster in ________________ than in liquids

• solids

• gas

• water

• air

A sound wave takes about 0.03 s to move through a material that is 10.3 m long. What is the material?

• air

• glass

• iron

• water

Movie theaters use sound proofing to reduce echoes. Soundproofing materials are designed to the sound.

• Absorption

• Transmission

• Diffraction

• Reflection

When a wave strikes a surface and bounces off (ex: echo)

• medium

• refraction

• reflection

• absorption

Which type of interaction is this?

• reflection
