Shinnecock Light
Shinnecock Light was a lighthouse on the south side of Long Island, New York. The name comes from the Shinnecock Indian Nation. The original red brick tower was built in 1858. It was tall and had a 1st order Fresnel lens, itself almost tall. If it were still standing it would be one of the ten tallest lighthouses in the US. It was discontinued in 1931 in favor of a skeleton tower and demolished by the Coast Guard in 1948. Some time later the Coast Guard A coast guard or coastguard is a Maritime Security Regimes, maritime security organization of a particular country.

Long Island
Long Island is a densely populated island in the southeastern region of the U.S. state of New York, part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the 18th-most populous in the world. The island begins at New York Harbor approximately east of Manhattan Island and extends eastward about into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four counties: Kings and Queens counties (the New York City boroughs of Brooklyn and Queens, respectively) and Nassau County share the western third of the island, while Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens. Culturally, many people in the New York metropolitan area colloquially use the term "Long Island" (or "the Island") to refer exclusively to Nassau and Suffolk counties, and con ...

New York (state)
New York, officially the State of New York, is a state in the Northeastern United States. It is often called New York State to distinguish it from its largest city, New York City. With a total area of , New York is the 27th-largest U.S. state by area. With 20.2 million people, it is the fourth-most-populous state in the United States as of 2021, with approximately 44% living in New York City, including 25% of the state's population within Brooklyn and Queens, and another 15% on the remainder of Long Island, the most populous island in the United States. The state is bordered by New Jersey and Pennsylvania to the south, and Connecticut, Massachusetts, and Vermont to the east; it has a maritime border with Rhode Island, east of Long Island, as well as an international border with the Canadian provinces of Quebec to the north and Ontario to the northwest. New York City (NYC) is the most populous city in the United States, and around two-thirds of the state's populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), 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 signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shinnecock Indian Nation
The Shinnecock Indian Nation is a federally recognized tribe of historically Algonquian-speaking Native Americans based at the eastern end of Long Island, New York. This tribe is headquartered in Suffolk County, on the southeastern shore. Since the mid-19th century, the tribe's landbase is the Shinnecock Reservation within the geographic boundaries of the Town of Southampton. Their name roughly translates into English as "people of the stony shore". History The Shinnecock were among the thirteen Indian bands loosely based on kinship on Long Island, which were named by their geographic locations, but the people were highly decentralized. The most common pattern of indigenous life on Long Island prior to their economic and cultural destruction - and, on occasion, actual enslavement - by the Europeans was the autonomous village linked by kinship to its neighbors.

List Of Lighthouses In The United States By Height
The height of existing lighthouses is expressed in two measures: the height of the tower itself, and the distance from the focal plane (that is, the center) of the light source to the water. The latter can be much greater than the former if the light stands on a promontory. Several structures which have functioned as lighthouses exceed the height of any entry in this list, among them the Statue of Liberty at and Perry's Victory and International Peace Memorial at . These are not listed because they were not constructed as lighthouses ''per se''. Tallest Lighthouses Highest focal plane # 462 feet (141 m) - Old Point Loma lighthouse, California # 422 feet (129 m) - Cape Mendocino Light, California # 420 feet (128 m) - Makapuu Point Light, Hawaii # 395 feet (120 m) - Navassa Island Light, Navassa Island # 358 feet (109 m) - Farallon Island Light, California # 294 feet (90 m) - Point Reyes Light, California # 278 feet (76 m) - Marcus Hook Range Rear Light, Delaware ...
