chapter one Flashcards
1
Q
Boundary
A
The surface of separation between two media.
2
Q
Incident Ray
A
A ray of light falling on the boundary
3
Q
Point of Incidence
A
The point at which the incident ray meets the boundary.
4
Q
Medium of Incidence
A
The medium in which the incident ray propagates.
5
Q
Normal
A
An imaginary straight line passing through the point of incidence and perpendicular to the flat boundary or the tangent plane to a curved boundary at the point of incidence.
6
Q
Reflected Ray
A
The ray that bounces off the boundary back into the medium of incidence.
7
Q
Angle of Incidence
A
The angle that the incidence makes with the normal at the point of incidence.
8
Q
Angle of Reflection
A
The angle the reflected ray makes with the normal at the point of incidence.
