Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays:
Following the long-term strategy by Swinburne Australia, [2] and the approval of the then Minister of Education of Malaysia, Najib Tun Razak in 1999, [5] the Swinburne Sarawak Institute of Technology was set up within a State Office Complex building at Jalan Simpang Tiga, Kuching, Sarawak.
The name "Kuching" was already in use for the city by the time Brooke arrived in 1839. [9] [15] There are many theories as to the derivation of the name "Kuching".It was perhaps derived from the Malay word for cat, "kucing", or from Cochin, an Indian trading port on the Malabar Coast and a generic term in China and British India for trading harbour.

The principal ray or chief ray (sometimes known as the b ray) in an optical system is the meridional ray that starts at an edge of an object and passes through the center of the aperture stop. [ 5 ] [ 8 ] [ 7 ] The distance between the chief ray (or an extension of it for a virtual image) and the optical axis at an image location defines the ...
RMAF Kuching was established in 1964 by the Royal Air Force during the Indonesia–Malaysia confrontation to strengthen defense in Sarawak.RMAF formed a small detachment to assist RAF with the stationed of 20 personnel with one Twin Pioneer and four Aérospatiale Alouette III in August 1966.
Ray optics explanation (focused laser). In addition to keeping the bead in the center of the laser, a focused laser also keeps the bead in a fixed axial position: The momentum change of the focused rays causes a force towards the laser focus, both when the bead is in front (left image) or behind (right image) the laser focus.
