X-rays are applied in medicine for scientific analysis. Dentists use them to discover complications, cavities and impacted tooth. Soft body tissues are apparent to the waves. Bones and tooth block the rays and show up as white on the black background. We find out the use of x-ray as a...
X-rays are used in industry to find hidden cracks in metal, and in medicine to reveal broken bones. 4. Usually we use electricity to generate electromagnetic energy. The source of most of our energy is the sun. Heat from the sun causes water to evaporate. When the water falls to the ...
It has been, however, successfully used in oncology (radiotherapy), physiotherapy (microwaves), rheumatology and endocrinology. Effective communication and data transmission are possible thanks to radio-, micro- and infrared waves. Cybernetics and modern forms of communication have been instrumental in ...

T.Rijavec,S.Bračko, inSmart Textiles for Medicine and Healthcare, 2007 7.2.1Photochromic compounds Photochromism is a reversible photochemical process during which a photochromic material temporarily changes its chemical structure and, consequently, also its electromagnetic waves absorption spectrum under ...
Electromagnetic radiation, in classical physics, the flow of energy at the speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves and visible l
The background of The system of maridians and collaterals is a heterogeneous distribution ofelectromagnetic field which comes from the superposition of standing waves in a body.In the other words,the main part of The system of maridiansund collaterals is an invisible interference pattern ofelectromag...
Field Intensity versus Wave Intensity of electromagnetic waves. A plane harmonic electro- magnetic wave in the vacuum or the air has electric and magnetic field intensity components, given by the equations: E = E0 sin(kwr − ωt) (1) B = B0 sin(kwr − ωt) (2) Scientific ...
In addition, in many studies only mobile phones are used instead of signal generators that allow for a more reproducible application of the signal. Furthermore, if the applied EMF at the location of the head is not accurately measured, the local power density and its spatial variation in the...
