Question | Answer |

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 |
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 ___________. | Regular reflection |
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 |
