The Scheinergrade (Sch.) system was devised by the German astronomer Julius Scheiner (18581913) in 1894 originally as a method of comparing the speeds of plates used for astronomical photography. Scheiner's system rated the speed of a plate by the least exposure to produce a visible darkening upon development. Speed was expressed in degrees Scheiner, originally ranging from 1 Sch. to 20 Sch., where an increment of 19 Sch. corresponded to a hundredfold increase in sensitivity, which meant that an increment of 3 Sch. came close to a doubling of sensitivity.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the second use of the Scheinergrade system?
Ah, so.. unanswerable

As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): A term that refers to the highs and lows of power in electro magnetic waves is?
Ah, so.. standing wave ratio

Ottoman Divan poetry was a highly ritualized and symbolic art form. From the Persian poetry that largely inspired it, it inherited a wealth of symbols whose meanings and interrelationshipsboth of similitude ( mura'at-i nazir / tenasub) and opposition ( tezad) were more or less prescribed. Divan poetry was composed through the constant juxtaposition of many such images within a strict metrical framework, thus allowing numerous potential meanings to emerge. The vast majority of Divan poetry was lyric in nature: either gazels (which make up the greatest part of the repertoire of the tradition), or kasides. There were, however, other common genres, most particularly the mesnevi, a kind of verse romance and thus a variety of narrative poetry; the two most notable examples of this form are the Leyli and Majnun of Fuzuli and the Husn u Ask of Seyh Galib.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of Ottoman poetry is ritualized?
Ah, so..
Divan poetry
