Superposition and Reflection of Waves

Reflection is...

• The frequency an object vibrates at when disturbed by an outside force.

• When an object is forced to vibrate at a specific frequency by an incident wave.

• When waves his a surface and bounce back the way they came.

• When an object is forced to vibrate at it's natural frequency.
