Wave Interactions with Objects

• When waves come in contact with objects, these interactions can occur.

• Absorption

• Transmission

• Reflection

• Refraction

• Diffraction

• **Interference

Absorption

Absorption occurs when an object takes in a wave as the wave hits it.

​

​

Transmission

Transmission is the passing of a wave through an object.

​

Reflection involves a change in direction of waves when they bounce off a barrier.
