Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity or amplitude and quantity of energy. This interactive tutorial explores the relationship between frequency, wavelength, and energy, and enables the visitor to adjust the intensity of the radiation and to set the wave into motion. The tutorial initializes with a visible light wave appearing in the window having a wavelength of nanometers red light and amplitude of 61 candelas. To adjust the wavelength and simultaneously, the frequency of the wave, translate either the Wavelength or Frequency sliders to the left or right. As the sliders are relocated, the new values for wavelength and frequency appear above the sliders, the wave color changes to match the value for visible light associated with the wavelength, and the energy associated with the wave appears beneath the tutorial window. The amplitude of the wave can be adjusted with the Amplitude slider, and the resulting intensity values will appear above the slider, measured in units of candelas. In order to stop propagation of the wave, click on the Propagation Stop button located in the lower right-hand side of the tutorial window.

Mechanical and Electromagnetic Vibrations and Waves

By George Bekefi and Alan H. The book describes the features that vibrations and waves of all sorts have in common and includes examples of mechanical, acoustical, and optical manifestations of these phenomena that unite various parts of physics. The main emphasis, however, is on the oscillatory aspects of the electromagnetic field—that is, on the vibrations, waves, radiation, and the interaction of electromagnetic waves with matter. This text was developed over a five-year period during which its authors were teaching the subject. It is the culmination of successful editions of class notes and preliminary texts prepared for their one-semester course at MIT designed for sophomores majoring in physics but taken by students from other departments as well. The content is designed primarily for the use of second or third year students of physics who have had a semester of mechanics and a semester of electricity and magnetism.

Named after esteemed physicist James Clerk Maxwell, the equations describe the creation and propagation of electric and magnetic fields. Fundamentally, they describe how electric charges and currents create electric and magnetic fields, and how they affect each other. Magnetic field lines form loops such that all field lines that go into an object leave it at some point. Thus, the total magnetic flux through a surface surrounding a magnetic dipole is always zero. Field lines caused by a magnetic dipole : The field lines created by this magnetic dipole either form loops or extend infinitely. The principle behind this phenomenon is used in many electric generators.

Стратмор протянул Сьюзан газетную вырезку. Это был перевод рекламного сообщения Никкей симбун, японского аналога Уолл-стрит джорнал, о том, что японский программист Энсей Танкадо открыл математическую формулу, с помощью которой можно создавать не поддающиеся взлому шифры. Формула называется Цифровая крепость, говорилось в заметке, и доступна для ознакомления в Интернете. Программист намеревался выставить ее на аукционе и отдать тому, кто больше всех заплатит.

Он может стереть все файлы, или же ему придет в голову напечатать улыбающиеся рожицы на документах Белого дома. Голос Фонтейна по-прежнему звучал спокойно, деловито: - Можете ли вы его остановить. Джабба тяжко вздохнул и повернулся к экрану.

 - Говорит Лиланд Фонтейн. Слушайте меня внимательно… ГЛАВА 112 - Надеюсь, вы знаете, что делаете, директор, - холодно сказал Джабба.  - Мы упускаем последнюю возможность вырубить питание. Фонтейн промолчал. И словно по волшебству в этот момент открылась дверь, и в комнату оперативного управления, запыхавшись, вбежала Мидж. Поднявшись на подиум, она крикнула: - Директор. На коммутатор поступает сообщение.

Сьюзан бессильно прижалась к двери, за которой, всего в нескольких сантиметрах от нее, работала вентиляция, и упала, задыхаясь и судорожно хватая ртом воздух. Сьюзан закрыла глаза, но ее снова вывел из забытья голос Дэвида. Беги, Сьюзан. Открой дверцу. Спасайся.

 - Переходите к главному. - Вернитесь назад, - приказала Сьюзан.  - Документ слишком объемный. Найдите содержание. Соши открутила несколько страниц. Механизм атомной бомбы A) альтиметр B) детонатор сжатого воздуха C) детонирующие головки D) взрывчатые заряды E) нейтронный дефлектор F) уран и плутоний G) свинцовая защита Н) взрыватели II. Ядерное делениеядерный синтез A) деление (атомная бомба) и синтез (водородная бомба) B) U-235, U-238 и плутоний III.

We apologize for the inconvenience...

Стратмор дал маху. Но надо идти вперед, а не оглядываться все время.  - В трубке воцарилась тишина, и Джабба подумал, что зашел слишком .
