1. The index of refraction for vacuum is
2. A tangent line is parallel to a normal line
3. A normal line is perpendicular to the interface between material.
4. If one measures the index of refraction to be 1.1, this material would be
5. When we make multiple measurements, we can have more confidence in the index of refraction
6. The index of refraction has units of distance.
7. The imaginary line perpendicular to the incident ray onto a materials interface is known as a
