Bjargtangar Lighthouse
The Bjargtangar Lighthouse ( , regionally also ) is a lighthouse located on the cliffs of Látrabjarg in northwestern Iceland. It marks the westernmost point of Iceland and is the westernmost building of Europe. History and description The Bjargtangar Light Station was established in 1913. The present tower was built in 1948. It is two stories high, built of concrete, and painted entirely white. The lantern house is on the second floor and faces the sea. Because the lighthouse is on a high cliff, the light's focal plane is above the sea. The site (but not the tower) is open to visitors, although access is difficult.

Westfjords
The Westfjords or West Fjords ( is, Vestfirðir , ISO 3166-2:IS: IS-4) is a large peninsula in northwestern Iceland and an administrative district, the least populous administrative district. It lies on the Denmark Strait, facing the east coast of Greenland. It is connected to the rest of Iceland by a seven-kilometre-wide isthmus between Gilsfjörður and Bitrufjörður . The Westfjords are very mountainous; the coastline is heavily indented by dozens of fjords surrounded by steep hills. These indentations make roads very circuitous and communications by land difficult. In addition many of the roads are closed by ice and snow for several months of the year. The Vestfjarðagöng road tunnel from 1996 has improved that situation. The cliffs at Látrabjarg comprise the longest bird cliff in the northern Atlantic Ocean and are at the westernmost point in Iceland. The Drangajökull glacier is located in the north of the peninsula and is the fifth-largest of the country, but the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Látrabjarg
Látrabjarg () is a promontory and the westernmost point in Iceland. The cliffs are home to millions of birds, including puffins, northern gannets, guillemots and razorbills. It is vital for their survival as it hosts up to 40% of the world population for some species such as of the razorbill. It is Europe's largest bird cliff, 14 km long and up to 440 m high.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...
