What are the three key interactions of waves mentioned in the text?

• Diffraction, refraction, and reflection

• Absorption, transmission, and scattering

• Reflection, absorption, and transmission

• Refraction, scattering, and absorption

What is diffraction?

• When waves change speed and direction

• When waves bounce back after hitting a surface

• When waves bend around obstacles or spread out

• When waves are absorbed by a medium

What happens during refraction?

• Waves are absorbed by a medium

• Waves change speed and direction

• Waves bounce back after hitting a surface

• Waves spread out after passing through small openings

Which wave interaction explains why you can see your image in a mirror?

• Diffraction

• Refraction

• Reflection

• Absorption

Why can you hear someone speaking even if they are around a corner?

• Because of refraction

• Because of reflection

• Because of diffraction

• Because of absorption
