Wave Properties of Light

(pg.546-550)

-Relection

-Refraction

-Diffraction

-Interference

Reflection
-when a wave strikes an object and bounces off
(Normal-cuts incident deam and reflected beam in half)
Spectular & Diffuse Reflection
.Specular-Smooth surface, equivalent repection
.Diffuse-Rough surface
Law of Reflection-states the angle of incidenc equals the angle of reflection.

Refraction
-bending of waves when passing from one medium to another.
-caused by change in speed
.slower (more dense)-light bends toward the normal
.faster (less dense)-light bends away from the normal
refraction depends on...
-speed of light in the medium
-wavelength of the light-shorter wavelengths(blue)bends more
less dense to more dense makes light bend

Diffaction
-opposite of medium
-bending of light waves
-red waves bend more than blue

Interference
Constructive=brighter light
Destructive=dimmer light
