Spherical geometry is the geometry of the two-dimensional surface of a sphere. Long studied for its practical applications – spherical trigonometry – to navigation, spherical geometry bears many similarities and relationships to, and important differences from, Euclidean plane geometry. The sphere has … Zobraziť viac In plane (Euclidean) geometry, the basic concepts are points and (straight) lines. In spherical geometry, the basic concepts are point and great circle. However, two great circles on a plane intersect in two antipodal points, … Zobraziť viac Because a sphere and a plane differ geometrically, (intrinsic) spherical geometry has some features of a non-Euclidean geometry and is sometimes described as … Zobraziť viac Spherical geometry has the following properties: • Any two great circles intersect in two diametrically … Zobraziť viac • Spherical astronomy • Spherical conic • Spherical distance • Spherical polyhedron Zobraziť viac Greek antiquity The earliest mathematical work of antiquity to come down to our time is On the rotating sphere (Περὶ κινουμένης σφαίρας, Peri … Zobraziť viac If "line" is taken to mean great circle, spherical geometry obeys two of Euclid's postulates: the second postulate ("to produce [extend] a finite straight line continuously in a … Zobraziť viac • Meserve, Bruce E.

Web2. jún 2014 · 1. To add to Carl Witthoff's answer: a plane wave won't simply become spherical just by propagating. One piece of background you seem to be lacking is this: plane waves are eigenmodes of freespace (or of any homogeneous medium), meaning they do not change their form by propagation (aside from taking on a phase delay) in a homogeneous … Web26. nov 2024 · Squares are also similar because they meet both conditions 1 and 2.
