3 The change in direction of a propagating wave, such as light or sound
5 To move, lie, or extend in different directions from a common point; branch off.
6 A ray that passes through the axis of an optical fiber.
7 The point on the axis of a lens or mirror to which parallel rays of light converge or from which they appear to diverge after refraction or reflection
8 The angle which the indecent ray makes the normal equal to the angle and the reflected Ray make the same normal
9 When a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant.
10 To scatter or cause to scatter; disseminate; disperse
11 To tend to meet in a point or line; incline toward each other, as lines that are not parallel.
13 A ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.
14 Curved like a segment of the interior circle
1 the branch of physics which involves the behaviour and properties of light
2 Aray that does not propagate in a plane that contains both the object point and the optical axis.
4 The angle between the surface normal and the reflected ray
12 A two-dimensional surface, any two of whose points can be joined by a straight line that lies entirely in the surface.
