What is the theory of electromagnetic waves?
The concept known as the theory of electromagnetic wave came from the work of James Clerk Maxwell and Heinrich Hertz. According to the electrical and magnetic equations of the assumed Maxwell, electromagnetic fields resemble a wave both in both the structure and the action. Electromagnetic waves coincide with measuring the speed of light, so the light itself the electromagnetic waves itself. Likewise, magnetic fields will do the same for electric fields, so both concepts work unison. Together, both fields oscillate and create an electromagnetic wave.
The physical properties of the theory of electromagnetic waves take the form of electrodynamics. This aspect of theory means that any electromagnetic field present in the same space is considered to be a vector field, a wave of direction and length. Therefore, it can be merge together with other vector fields. For example, when the electromagnetic wave affects the molecule, the atoms in this molecule begin to oscillate and radiate their own electromagnetic waves, which affects the original inflax. According to the theory of electromagnetic wave, this causes a quarry, a change in speed or diffraction, a change in wavelength.
Because light is a type of electromagnetic wave, theory determines that light oscillation cannot be influenced by other static electrical or magnetic fields. However, the interaction between certain external events, such as the light passing by a crystal, may have an effect. According to the theory of electromagnetic waves, magnetic fields affecting the light of Faraday and the electrical fields affecting light will cause the Kerra effect to reduce the speed of light waves.
Frequencyis a very important aspect of the theory of electromagnetic wave. The oscillation of the wave is measured by Hertz, the frequency of the beetle. One hertz equals one oscillation per second. When an electromagnetic wave, as in the case of light, creates waves at different frequencies, is considered a spectrum.
Small energy particles called photons jSOU basic units of electromagnetic radiation. As the photons travel, the wool follows and creates a frequency in proportion to the particle. Photons are absorbed by atoms that in turn exciting electrons. When the electron reaches a sufficiently high energy level, it escapes the positive attraction of the core. If the energy level decreases, photon light is emitted.
The theory of electromagnetic waves states that any acceleration of electric charge or change of magnetic field creates radiation. This radiation may come in the form of a wool or particle. Speed, wavelength and frequency are factors associated with waves. The particles contain individualized energy straight frequency. Regardless of TTYP, electromagnetic radiation travels at the speed of light in the vacuum. This has forced Albert Einstein to create the theory of relativity.
