• 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 Incident Angle of Reflection
45º45º
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
As light passes through a material the speed of light will slow down and bend
Refraction is the BENDING of light waves.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 isDiffused or scattered in many directions. DIFFRACTION p.550The Law of reflection stays the same. But the light isDiffused or scattered in many directions. DIFFRACTION p.550
INTERFERENCEp. 551-552
• 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.
