The elements are mounted in a mechanical assembly so that the facing faces are parallel and located close together. The thin ends of the prisms in each element are at opposing ends of the element. The angles (A1,2) subtended by the prisms and their refractive indices are chosen to reduce ...
If two diameters of a circle intersect each other at right angles, t... 03:11 If A B C is an arc of a circle and /A B C=135^0, then the ratio of... 01:52 The chord of a circle is equal to its radius. The angle subtended by... 02:36 P Q R S is a cyclic quadrilate...
the distance subtended at Earth’s surface by some fixed angle of longitude changes with the latitude where that distance is measured. At North or South poles, that distance will become zero as all longitudes collapse to the same point, the pole. Along the Equator, that distance will be ...
