If a ray tracing is then made as if a light wave ( as understood in classical physics ) is wide enough to take both paths, then that ray tracing will accurately predict the appearance of maxima and minima on the detector screen when many particles pass through the apparatus and gradually " paint " the expected interference pattern.

If and ray
If, in an unsharp image, a patch of light corresponds to an object point, the center of gravity of the patch may be regarded as the image point, this being the point where the plane receiving the image, e. g., a focusing screen, intersects the ray passing through the middle of the stop.
If there is little rearrangement of radiosity objects in the scene, the same radiosity data may be reused for a number of frames, making radiosity an effective way to improve on the flatness of ray casting, without seriously impacting the overall rendering time-per-frame.
If the surface at this point faces a light, a ray ( to the computer, a line segment ) is traced between this intersection point and the light.
If the quantity under the square root ( the discriminant ) is negative, then the ray does not intersect the sphere.

If the ray of light strikes a surface lower than this angle, it will leave the gem material instead of reflecting through the gem as brilliance.
If the ray passes exactly through a vertex of a polygon, then it will intersect 2 segments at their endpoints.
The issue is solved as follows: If the intersection point is a vertex of a tested polygon side, then the intersection counts only if the second vertex of the side lies below the ray.
If the polygon is specified by its vertices, then this problem is eliminated by checking the y-coordinates of the ray and the ends of the tested polygon side before actual computation of the intersection.
If an atom is at the edge of the grid, any ray which is aimed into the grid directly beside it causes a reflection.
If and tracing

If the system is set to detect this vulnerability, it will recognize that it is under attack and can respond, either by locking the system down until proper administrators have a chance to react, by monitoring the attack and tracing the assailant, or by disconnecting the attacker.
If a greatly enlarged image of a segment of a phonautograph tracing were projected as a horizontally-oriented undulating line on a sheet of graph paper, a numerical description of the line could be created by proceeding from one grid column to the next, counting the number of squares between the line and a straight horizontal reference line, and making a list of the numbers.
After The Last Tycoon ( March 14, 1957 ), adapted from the F. Scott Fitzgerald novel about a film studio head, Frankenheimer followed with Tad Mosel's If You Knew Elizabeth ( April 11, 1957 ) about an ambitious college professor ; another Fitzgerald adaptation, Winter Dreams ( May 23, 1957 ), dramatizing a romantic triangle ; Clash by Night ( June 13, 1957 ), with Kim Stanley in an adaptation of the Clifford Odets play ; and The Fabulous Irishman ( June 27, 1957 ), a biographical drama tracing events in the life of Robert Briscoe.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.
