Section 3: Behavior of Waves. Reflection Reflection occurs when a wave strikes an object and bounces off of the object. All types of waves (water, sound,

How do waves interact?. Reflection Reflection: Happens when a wave bounces back after hitting a barrier. Reflection: Happens when a wave bounces back.

Chapter 29 Reflection and Refraction. When waves interact with matter, they can be reflected, transmitted, or a combination of both. Waves that are transmitted.

Wave Information. 1.A wave is an oscillation or back and forth OR up and down movement. 2. Waves that travel through matter are called mechanical waves.

Absorption : p.548 transfer of energy to the medium » Depends on type of material Transmission: p.458 passage light through an object

LAW OF REFLECTION Angle of IncidentAngle of Reflection 45º Angle of Incident = Angle of Reflection

LAW OF REFRACTION WATER Angle of Incident Angle of Refraction As light passes through a material the speed of light will slow down and bend Refraction is the BENDING of light waves.

Why doesn’t this work on all surfaces? Rough Surface The Law of reflection stays the same. But the light is Diffused or scattered in many directions. DIFFRACTION p.550 The Law of reflection stays the same. But the light is Diffused or scattered in many directions. DIFFRACTION p.550

INTERFERENCE p When waves…. Overlap Combine Forming a new wave Constructive…a new wave forms by overlap (higher Amplitude) Destructive…crest and trough meet (lower Amplitude)

What causes a shadow? Shadows are created by blocking the flow of light as it travels in a straight path.
