| ray | A geometric representaion of a light path through an optical medium - a line normal to the wave front indicating the direction of radiant energy flow. |
| ray | A beam of electromagnetic energy following an elemental path perpendicular to the radiation's wave front. |
| ray | A ribbon like figure caused by the strands of cells which extend across the grain in quarter sawn lumber. |
| ray | Given a region G c R2 A ray is a piecewise linear path with corners lying on a point p at the boundary of G respecting the usual law of reflection with the tangent line at p Given a region H c R3, the ray behaves as in R2 with the tangent plane Further, the incident and reflected portion of a ray are coplanar with the surface normal at p.
