This action allows the chemical mechanisms that underlie human vision and plant photosynthesis. Collective oscillation of charge carriers in bulk material plasma oscillation.

Amplifier combiner splitter network. These relations are illustrated by the following equations:. When EM radiation interacts elektromagnerisch single atoms and molecules, its behavior also depends on the amount of energy per quantum photon it carries.

The ancient Greeks recognized that light traveled in straight lines and studied some of its properties, including reflection and refraction. See pages I-7 atmosphere and I for water. Cool Cosmos Classroom activities. If radiation having a frequency in the visible region of the EM spectrum reflects off an object, say, a bowl of fruit, and then strikes elsktromagnetisch eyes, this results in visual perception of the scene.

Transmittance verre ambre alimentaire. One notable use is diagnostic X-ray imaging in medicine a process known as radiography. Elektromatnetisch electromagnetic spectrum is the range of frequencies the spectrum of electromagnetic radiation and their respective wavelengths and photon energies.

  ADG1434 DATASHEET PDF

The wavelength of gamma rays can be measured with high accuracy through the effects of Compton scattering. Media in category “Electromagnetic spectrum” The following 79 files are in this category, out of 79 total.

Hue Dichromatism Colorfulness chroma and saturation Tints and shades Lightness tone and value Grayscale. Electromagnetism portal Electronics portal Telecommunication portal. These photons were from Lyman series transitions, putting them in elekktromagnetisch ultraviolet UV part of the electromagnetic spectrum.

The Florida State University.

Retrieved from ” https: For example, Hertz was able to focus the waves using a lens made of tree resin. Leds sodium spectrum fr. Electromagnetic waves are typically described by elektroomagnetisch of the following three physical properties: In other projects Wikimedia Commons Wikipedia.

This page was last edited on 14 Decemberat In a later experiment, Hertz similarly produced and measured the properties of microwaves. Excitation of molecular and atomic valence electrons, including ejection of the electrons photoelectric effect.

On average, a maximum load of 0. Spectre onde electromagnetique flipped. It can be divided into three parts: This classification goes in the increasing order of wavelength, which is characteristic of the type of radiation.

The behavior of EM radiation depends on its wavelength. In a radio communication system, a radio frequency current is modulated with an information-bearing signal in a transmitter by varying either the amplitude, frequency or phase, and applied to an antenna.

The radio waves carry the information across space to a receiver, where they are received by an antenna and the information extracted by demodulation in the receiver. Origins and Grand Finale: Energetic ejection of core electrons in heavy elements, Compton scattering for all atomic numbersexcitation of atomic nuclei, including dissociation of nuclei.

Electromagnetic spectrum

It is clear that the introduction of Wi-Fi in urban locations basically does not contribute to the electromagnetic radiation that is currently present. This page was last edited on 21 Octoberat Home Technology Wi-Fi and health. In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna.

This startling coincidence in value led Maxwell to make the inference that light itself is a type of electromagnetic wave.
