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.

Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light. Specialized instruments onboard NASA spacecraft and airplanes collect data on how electromagnetic waves behave when they interact with matter. These data can reveal the physical and chemical composition of matter.

Tour of the Electromagnetic Spectrum

Electromagnetic waves have a vast range of practical everyday applications that includes such diverse uses as communication by cell phone and radio broadcasting, WiFi, cooking, vision, medical imaging, and treating cancer. In this module, we discuss how electromagnetic waves are classified into categories such as radio, infrared, ultraviolet, and so on. We also summarize some of the main applications for each range. The different categories of electromagnetic waves differ in their wavelength range, or equivalently, in their corresponding frequency ranges. Their properties change smoothly from one frequency range to the next, with different applications in each range. The term radio waves refers to electromagnetic radiation with wavelengths greater than about 0.

The behaviour of an electromagnetic wave in a substance depends on its frequency or wavelength. The differing behaviours of different groups in the electromagnetic spectrum make them suitable for a range of uses. Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction.

The Electromagnetic Spectrum

The electromagnetic spectrum ranges from the shorter wavelengths including gamma and x-rays to the longer wavelengths including microwaves and broadcast radio waves. There are several regions of the electromagnetic spectrum which are useful for remote sensing. For most purposes, the ultraviolet or UV portion of the spectrum has the shortest wavelengths which are practical for remote sensing. This radiation is just beyond the violet portion of the visible wavelengths, hence its name. Some Earth surface materials, primarily rocks and minerals, fluoresce or emit visible light when illuminated by UV radiation.

16.6: The Electromagnetic Spectrum

This paper presents an electromagnetic radiation-based method to qualitatively assess mine-induced stress field at the longwall face. We first analyze the correlation between electromagnetic EM signals and stress, and then measure the signals and drilling bits in both the strike and dip directions at the working face of Nuodong Coal Mine, China, which indirectly verifies this method. Results show that there is a positive correlation between EM intensity and stress.

We apologize for the inconvenience...

Geosynchronous satellite is placed in the geosynchronous orbit with an orbital period matching the Earth's rotation period. These satellites take 24 hours to complete one rotation around the earth. However, the orbital plane for a typical geosynchronous satellite is generally not the equatorial plane.

Ее белая блузка промокла насквозь и прилипла к телу. Было темно. Сьюзан остановилась, собираясь с духом.

1. Introduction

В воздухе стоял тяжелый запах мочи. Лампочки в конце коридора не горели, и на протяжении последних двадцати метров можно было различать только смутные силуэты. Женщина с кровотечением… плачущая молодая пара… молящаяся маленькая девочка. Наконец Беккер дошел до конца темного коридора и толкнул чуть приоткрытую дверь слева. Комната была пуста, если не считать старой изможденной женщины на койке, пытавшейся подсунуть под себя судно. Хорошенькое зрелище, - подумал Беккер.  - Где, черт возьми, регистратура.

Ему не нужно было напоминать, что произойдет, если три миллиона процессоров перегреются и воспламенятся. Коммандеру нужно было подняться к себе в кабинет и отключить ТРАНСТЕКСТ, пока никто за пределами шифровалки не заметил этой угрожающей ситуации и не отправил людей им на помощь. Стратмор бросил взгляд на лежавшего в беспамятстве Хейла, положил беретту на столик рядом со Сьюзан и крикнул, перекрывая вой сирены: - Я сейчас вернусь! - Исчезая через разбитое стекло стены Третьего узла, он громко повторил: - Найди ключ.

Сьюзан встала. Чрезвычайная ситуация. Она не помнила, чтобы это слово срывалось когда-нибудь с губ коммандера Стратмора. Чрезвычайная. В шифровалке.

 - Я думаю, - начала она, -что я только… -но слова застряли у нее в горле. Она побледнела. - Что с тобой? - удивленно спросил Хейл.

Наконец Нуматака спросил: - Где ключ. - Вам нужно знать только одно: он будет найден. - Откуда такая уверенность. - Не я один его ищу. Американская разведка тоже идет по следу.

 - Дэвид… Все пришли в смятение. Сьюзан шла вперед, повторяя это имя, ее глаза неотрывно смотрели на экран. - Дэвид! - воскликнула она, еле держась на ногах.

In this module we examine how electromagnetic waves are classified into categories such as radio, infrared, ultraviolet, and so on, so that we can understand some of their similarities as well as some of their differences.

In physics , radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
