10 Electromagnetic waves are produced by the motion of electrically charged particles. Infrared Radiation: Infrared radiation is the band of electromagnetic radiation that occupies wavelengths between 0.74 micrometers up to 300 micrometers. Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. in various activities within the electromagnetic environment. HEAT Solar electromagnetic radiation is generated by the extremely hot plasma of the Sun, and this thermal radiation heats the Earth by the reverse process of absorption, generating kinetic, thermal energy in electrons and atomic nuclei. For this reason, experts refer to electromagnetic radiation as the ‘far-field.’ 4. The idea of using a signal lamp to communicate was used in the 19th century. Infrared radiation is very close to optical light, and therefore very similar techniques are … Electromagnetic radiation having many hazardous effects on human beings and other living forms has the other side of having disease curing effect. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. The uses of electromagnetic waves, this section describes some of the qualities and uses of different waves on the electromagnetic spectrum. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected. The Earth also emits thermal radiation, but at a much lower intensity because it is cooler. These equations state that electromagnetic radiation consists of quantized, traveling fluctuations in the electromagnetic field. However, we must emphasize the importance of remaining alert to the danger of overexposure to electromagnetic radiation. Many people think that electromagnetic radiation is not dangerous, while there are others in the scientific community who are still doing studies on this subject. For GCSE physics revision. Examples of non-ionizing radiations are: • Static electromagnetic fields from direct current (0 Hz) • Low-frequency waves from electric power (50-60 Hz) • Extremely Low Frequency (ELF) The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. Electromagnetic Radiation (EMR) • is radiated by atomic particles at the source (the Sun), • propagates through the vacuum of space at the speed of light, • interacts with the Earth's atmosphere, • interacts with the Earth's surface, • interacts with the Earth's atmosphere once again, and Radiation is energy in the form of waves or particles that comes from a source and travels through space or through a medium. Electromagnetic Radiation (EMR), with energy levels below that required for effects at the atomic level. Electromagnetic (EM) radiation occurs both naturally (e.g., sunlight) and from man-made sources (e.g., wireless devices). The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. These are discussed in more detail later in this section but generally are used with the purpose of reducing pain, muscle spasms, inflammation, and/or improving superficial/deep circulation status and subsequent healing potential. The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi. The electromagnetic rays and radiations emitted by these elements is also of immense importance both medically and industrially. 8, 9 Wi-Fi equipped laptop computers have also been linked to decreased sperm motility and an increase in sperm DNA fragmentation after just four hours of use. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an … Electromagnetic radiation - Electromagnetic radiation - Relation between electricity and magnetism: As early as 1760 the Swiss-born mathematician Leonhard Euler suggested that the same ether that propagates light is responsible for electrical phenomena. The waves that are used in this way are radio waves, microwaves, infrared radiation and light. A discussion of the various methods used to detect electromagnetic energy is beyond the scope of this TRAMAN. Electromagnetic Radiation and Life: Bioelementological Point of View 195 influence of millimeter wave radiation there is observed increased accumulation of a number of trace elements from the environmen t: selenium, chromium, zinc, copper, lithium, etc., with dramatic change in elemental composition of the algal cells (Tambiev et al., 2000-2011). From the experiments of Hertz and others, Maxwell’s predictions that oscillating charges emitted electromagnetic radiation had been confirmed, at least for simple antennas. The purpose of this article is to dig into the details of what this electromagnetic radiation is, and to explore if there are any harmful effects of electromagnetic radiation on humans. As EM energy travels through the space, it behaves either longitudinal or transverse waves and it contains both components of electric and magnetic fields. Electromagnetic Radiation in Quantum Mechanics The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.. The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. Some traditional applications that use electromagnetic radiation include the entire family of therapies known as electrophysical agents. EMR Impairments To Immune System – The immune system is impaired in the presence of This method of long distance communication … Sources: Dr. Neal Cherry (2000), Burch et al. 7 Regions of the Electromagnetic Spectrum 769 Words | 4 Pages. Because the wavelength of electromagnetic radiation can be as long as 40 m or as short as 10-5 nm, the visible spectrum is only a small portion of the total range of electromagnetic radiation. Researchers Create an Electromagnetic "Black Hole" the Size of a Salad Plate. OR. Since thermal radiation is electromagnetic radiation, the properties of the propagation of electromagnetic waves can be applied. (There are 1 million micrometers in one meter.) In this piece of article, we will discuss electromagnetic radiation and its properties. Electromagnetic field produce electromagnetic radiation also referred to as EM radiation. Melatonin Reduction – Electromagnetic Radiation reduce the levels of melatonin in the human body. In comparison with both mechanics and optics, however, the science of electricity was slow to develop. Electromagnetic radiation: The Electromagnetic radiation are considered as a waves of the energy. Electromagnetic radiation is used for communications and transmission of information. Electromagnetic radiation above 2500 × 10 6 MHz is mostly referred to as ionizing radiation. In the case of propagation in a vacuum, c = c o = 2.998 × 10 8 m/s. Electromagnetic radiation exists across a wide range of frequencies and can be organized on a frequency spectrum as follows: radio waves, infrared waves, visible light, ultraviolet rays, x-rays, and gamma rays. Radiation: Here, Radiation is defined broadly to include charged particles such as alpha α and beta β radiation. Solar electromagnetic radiation is generated by the extremely hot plasma of the Sun, and this thermal radiation heats the Earth by the reverse process of absorption, generating kinetic, thermal energy in electrons and atomic nuclei. Ultraviolet rays are germicidal in nature and destroy bacteria, viruses and moulds from various surfaces, air or water. Electromagnetic radiation is a form of energy that is present all around us and takes various forms like microwaves, television waves, radio waves, gamma rays, X-rays, etc. Unfortunately, all of today’s technology emits Electromagnetic Radiation, or Electromagnetic Field (EMF) radiation, which can cause health problems over time which include fertility issues, DNA damage, electromagnetic hypersensitivity, and many other health concerns.
