|REFLECTION = ?
|When a light source comes into contact with a smooth, opaque object.
|Total Internal Reflection
|When the angle between light ray + normal > critical angle
|Angle at which the light source skims along the boundary.
|How does internal reflection occur?
|- Light must be travelling into a substance of lower optical density - Must strike at an angle greater than critical angle of incidence
|If the reflecting surface is very smooth, the reflection of light that occurs is called ___________.
|The Law of Reflection states that the __________ = __________.
|Angle of incidence; angle of reflection
|The _________, the _________, and the _________ all lie on the same plane.
|Incident ray; reflected ray; normal
|The ______ and the ______ are on the opposite sides of the ________.
|Reflected ray; incident ray; normal
