Characteristics of electromagnetic waves Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. 10. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length (1.616 x 10-35 m), although in principle the spectrum is infinite and continuous. SC.8.E.5.11: Identify and compare characteristics of the electromagnetic spectrum such as wavelength, frequency, use, and hazards and recognize its application to an understanding of planetary images and satellite photographs. Visible Light. When light passes through atoms, those atoms can absorb some of the light's energy. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. The electromagnetic spectrum (Table 13.1) interacting with local gas species, electrons, protons, cosmic rays, ions and the earth's magnetic field produces a space plasma which is a function of orbital parameters and solar activity [2].There are numerous mechanisms, related to this environment, by which a spacecraft can accumulate charge. Visible Light Rays. At very high energies, a single photon can create a shower of high-energy particles and antiparticles upon interaction with matter. Different regions of this wide range from the shortest wavelengths to the longest ones (equivalently from the highest frequencies to the lowest ones) are respectively named gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves and radio waves. CHARACTERISTICS OF RADIATION After reading this section you will be able to do the following: Explain what the electromagnetic spectrum is and how scientists use it. NASA's mission page on the electromagnetic spectrum explains how astronomers use X-rays. Accelerated charges are responsible to produce electromagnetic waves. This includes electromagnetic energy ranging from gamma rays to radio waves. Electromagnetic waves are defined by their special characteristics, Advanced Basic The Electromagnetic Spectrum The electromagnetic (EM) spectrum is the range of all types of EM radiation.Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. Electromagnetic waves are typically described by any of the following three physical properties: the frequency (f) (also sometimes represented by the Greek letter nu, ν), wavelength (λ), or photon energy (E). The behavior of electromagnetic radiation depends on its wavelength. Some spectrum (such as in the (UHF) band 300-3000 MHz) is known to be suitable for a wide variety of services and is in great demand. But when waves travel through space, no energy is lost. The different frequencies of … spectrumA range of colors representing light (electromagnetic radiation) of contiguous frequencies; hence electromagnetic spectrum, visible spectrum, ultraviolet spectrum, etc. But as you look closer, you see that the line is made up of thousands of separated black ants. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, … X-rays are a form of electromagnetic radiation; their basic physical properties are identical to those of the more familiar components of the electromagnetic spectrum—visible light, infrared radiation, and ultraviolet radiation. Ideal for AQA GCSE (9-1) P6, Cambridge iGCSE P7 and more. Wavelengths of electromagnetic radiation, no matter what medium they are traveling through, are usually quoted in terms of the vacuum wavelength, although this is not always explicitly stated. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. AnalogTravels in a continous waveStrength and frequency vary. Digital signal transmission information is converted to ones and zeros which are formatted and sent as electrical pulses. Any electromagnetic wave produced by currents in wires is classified as a radio wave, the lowest frequency electromagnetic … Visible: Molecular electron excitation (including pigment molecules found in the human retina), plasma oscillations (in metals only). When discovered by James Maxwell, this opened the window to better understand the workings of light and the unification of electricity, magnetism and optics under the same field. DigitalTravels as an electrical pulseMore accurate, less interference, Characteristics of Electromagnetic Spectrum, http://www.nasa.gov/directorates/heo/scan/spectrum/txt_characteristics_spectrum.html. Infrared waves, or infrared light, are part of the electromagnetic spectrum. The electromagnetic spectrum is separated into many categories and subcategories, based on the frequency and wavelength, source, and uses of the electromagnetic waves. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Electromagnetic_spectrum In general, signals sent using the higher frequencies have shorter propagation distances but a higher data-carrying capacity. Wave characteristics What is a wave? The relationship between frequency and wavelength in a vacuum for various types of EM waves is depicted in the Electromagnetic Spectrum, shown below. The characteristics of the electromagnetic spectrum are the propagation features and the amount of information which signals can carry. In general, signals sent using the higher frequencies have shorter propagation distances but Near infrared: Molecular vibration, plasma oscillation (in metals only). The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. When waves travel through matter, they lose some energy to the matter as they pass through it. The electromagnetic spectrum ranges from gamma rays (with shortest wavelength) to radio waves (with the longest wavelength). You can use the electromagnetic spectrum to answer questions about EM waves. A radio detects a Discoverers of Different Regions of Electromagnetic Spectrum Electromagnetic radiation has a wide range of frequencies or wavelengths. Infrared waves, or infrared light, are part of the electromagnetic spectrum. the distance from one point on one wave to the same exact point on the While, in general, the classification scheme is accurate, in reality there is often some overlap between neighboring types of electromagnetic energy.
