Here is a question about this article: Reflection of the original signal also occurs when it hits an extended conductive surface, in a fashion similar to a mirror. This effect can also be used to increase signal through the use of a reflector, normally placed behind the active element and spaced so the reflected signal reaches the element in-phase. Generally the reflector will remain highly reflective even if it is not solid; gaps less than 1⁄10 generally have little effect on the outcome. For this reason, reflectors often take the form of wire meshes or rows of passive elements, which makes them lighter and less subject to wind. The parabolic reflector is perhaps the best known example of a reflector-based antenna, which has an effective area far greater than the active element alone.
What is the answer to this question: What is the most recognized type of an antenna that has its basis in reflection?
****
So... parabolic reflector


Here is a question about this article: Before the war, many observers believed the US and its allies could win but might suffer substantial casualties (certainly more than any conflict since Vietnam), and that the tank battles across the harsh desert might rival those of North Africa during World War II. After nearly 50 years of proxy wars, and constant fears of another war in Europe between NATO and the Warsaw Pact, some thought the Persian Gulf War might finally answer the question of which military philosophy would have reigned supreme. Iraqi forces were battle-hardened after 8 years of war with Iran, and they were well equipped with late model Soviet tanks and jet fighters, but the antiaircraft weapons were crippled; in comparison, the US had no large-scale combat experience since its withdrawal from Vietnam nearly 20 years earlier, and major changes in US doctrine, equipment and technology since then had never been tested under fire.
What is the answer to this question: What problem did the Iraqi forces have?
****
So... the antiaircraft weapons were crippled


Here is a question about this article: Galicia has a surface area of 29,574 square kilometres (11,419 sq mi). Its northernmost point, at 43°47′N, is Estaca de Bares (also the northernmost point of Spain); its southernmost, at 41°49′N, is on the Portuguese border in the Baixa Limia-Serra do Xurés Natural Park. The easternmost longitude is at 6°42′W on the border between the province of Ourense and the Castilian-Leonese province of Zamora) its westernmost at 9°18′W, reached in two places: the A Nave Cape in Fisterra (also known as Finisterre), and Cape Touriñán, both in the province of A Coruña.
What is the answer to this question: What is its northernmost point?
****
So...
Estaca de Bares
