Stories about monsters depths are very common, with the appearance of witnesses mysterious creatures often people are quite credible. Illustrative case, which occurred with the famous writer Vsevolod Ivanov in Koktebel. One writer admired flock of dolphins, traveling on the bay. But after a while his attention was attracted large rock, overgrown with algae. This strange rock is about 50 meters from the shore, and its size was about 10-12 feet in diameter.
The writer was watching this tangle of seaweed. After a while for probably intensified as algae somehow began to lose regular round shape. Tangle was lengthened, and in the middle there were tears. Next best quote of the Vsevolod Ivanov
"Then I trembled to his feet and sat down, as if afraid that I can scare the" it "is, if I stand on my feet. I looked at the clock. It was 12.15. There was almost complete silence. Just behind me, in the valley Gyaur Bach, chirping birds. Heavily smoked my pipe. "Tangle" unfolded. Time-and-return. Stretched out. I still believed and did not think "it" algae, as long as "it" not moved against the current. This creature was swimming undulation to the place, where the Dolphins, that is, the left side of the bay. "
The author of this story, brought on theories saying that this can not be, painfully thought, is not it all a hallucination? He looked at the clock on them was 12.18. Despite the glare from the sun on the water, it was so clear, the body dolphins looked through quite clearly, although they were from the observer twice as far as the monster deep. The size of the monster was very impressive about 25-30 meters and its thickness match the width of the desk tops.
Monster depths, writhing in the same way as a swimming snake, smooth and quiet, like the Siberian cat, right towards the dolphins. Dolphins, seeing the creature, immediately fled. Banished, so dolphins monster again took the form of a coil, and the current was to attribute it to its original location. When it drifted to the middle of the bay, the monster suddenly depths again turned and turned in the direction of dolphins suddenly raised his head above the water. His head was the size of swing arms, and is shaped like a snake. Eye of the author saw, from which concluded that they were small. With a huge head dripping water, about two minutes monster held her above the water, and then abruptly turned and looked down into the water and swam with great speed over rocks that close Carnelian Bay.
This incident occurred May 14, 1952. The writer watched the monster more than 40 minutes. What he saw shocked him and prompted Vsevolod Ivanov begin searching information about a mysterious creature.
Длина́ волны́ — расстояние между двумя ближайшими друг к другу точками, колеблющимися в одинаковых фазах, обычно длина волны обозначается греческой буквой λ(лямбда). По аналогии с волнами, возникающими в воде от брошенного камня, длиной волны является расстояние между двумя соседними гребнями волны. Одна из основных характеристик колебаний. Измеряется в единицах расстояния (метры, сантиметры и т. п.).
Величина 
, обратная длине волны, называется волновым числом и имеет смысл пространственной частоты.
Получить соотношение, связывающее длину волны с фазовой скоростью (
) и частотой (
-ню) можно из определения. Длина волны соответствует пространственному периоду волны, то есть расстоянию, которое точка с постоянной фазой проходит за время, равное периоду колебаний 
, поэтому
λ=
Волнам де Бройля также соответствует определенная длина волны. Частице с энергией Е и импульсом p, соответствуют:
Частота: 
Длина волны: λ=
где h — постоянная Планка.

Объяснение:
Абу Наср ибн Мухаммед аль-Фараби[2][4], употребительное сокращение имени — аль-Фараби (в латинизированной форме — Alpharabius; 870 или 872[5], Фараб[6], совр. Казахстан — между 14 декабря 950 и 12 января 951[7], Дамаск[6], совр. Сирия) — философ, математик, теоретик музыки, учёный Востока. Один из крупнейших представителей средневековой восточной философии. Аль-Фараби — автор комментариев к сочинениям Аристотеля (отсюда его почётное прозвище «Второй учитель») и Платона. Его труды оказали влияние на ибн Сину, ибн Баджу, ибн Туфайля, ибн Рушда, а также на философию и науку средневековой Западной Европы. Ему приписывается создание Отрарской библиотеки.
