Properties of images formed by a plane mirrors: i The image formed by a plane mirror is virtual and erect. Properties of the image formed by a convex mirror: i This image is always virtual and erect. Laws of refraction of light: The refraction of light obeys the following two laws: First law: The incident ray, the refracted ray and normal to the surface of separation at the point of incidence, all lie in the same plane.

Light rays travel in different mediums at different speeds. This is the highest speed possible in physics. One of the most important parameters that measures optical properties of a medium is the index of refraction. The refractive index measure the optical density of a given material. A material with higher refractive is more optically dense than a material with lower refractive index.

Это шантаж. Больше всего похоже на требование выкупа. Слова Сьюзан прозвучали слабым, едва уловимым шепотом: - Это… Энсей Танкадо. Джабба повернулся и изумленно посмотрел на. - Танкадо. Сьюзан едва заметно кивнула: - Он требовал, чтобы мы сделали признание… о ТРАНСТЕКСТЕ… это стоило ему… - Признание? - растерянно прервал ее Бринкерхофф.

 А метод грубой силы? - предложил Бринкерхофф.  - Можно ли с его помощью найти ключ. Джабба всплеснул руками. - Ради всего святого. Шифры-убийцы похожи на любые другие - они так же произвольны. Угадать ключи к ним невозможно.

Халохот внимательно проследил взглядом всю ее длину. В дальнем конце три полоски света, прорываясь сквозь прорези, четкими прямоугольниками падали на брусчатку мостовой. Один из прямоугольников вдруг закрыла чья-то тень. Даже не взглянув на верхушку башни, Халохот бросился к лестнице.

В центре лба зияло пулевое отверстие, из которого сочилась кровь, заливая лицо. - О Боже! - воскликнул он в ужасе. - Esta muerta, - прокаркал за его спиной голос, который трудно было назвать человеческим.

Она, разумеется, знала, что были и другие программы, над которыми он работал так долго, программы, создать которые было куда легче, чем нераскрываемый алгоритм. Вирусы. Холод пронзил все ее тело. Но как мог вирус проникнуть в ТРАНСТЕКСТ.
