ξ denotes the angle between the tangent to the PKPdf ray and the Earth's rotational axis. The inner core boundary is denoted by ICB. IC, inner core; ICB, IC boundary. Research observing anisotropy variations in the upper part of the IC has been abundant (Cao & Romanowicz, 2004; Cr...

which states the reflection angle is equal to the incidence angle, this implies the required result, namely that a ray originating at F1F1 will reflect into F2F2, and vice versa, because the angle between PF1PF1 and the normal vector at PP is equal to the angle...
I need a curve such that every tangent plane makes equal angles with the two rays. I can figure out a lens, too, because every ray that comes to it is bent through an angle given by Snell's law.” Evidently the statement of least time and the statement that angles are equal on ...
The angle between the skier's path and the hill is 2.3 degrees when he lands just at the edge of the hill. This angle increases as his take-off point approaches the edge of the hill to approximately 17.862 degrees. The shape of a trajectory is a parabola, such that ...
