What exactly is the electromagnetic spectrum? Is a continuous range of wavelengths‚ which includes gamma rays‚ ultraviolet waves and other forms of electromagnetic radiation. How does the issue of scarcity and interference relate to the electromagnetic spectrum? The spectrum is considered scarce because of the limited number of frequencies for operation and two parties cannot broadcast on the same frequency in the spectrum. Interference not only can be caused by broadcasters but by natural phenomenons

Comparing Wavelengths In The Electromagnetic Spectrum Gamma rays have the smallest wavelength in the electromagnetic spectrum‚ there is only 0.03 nano meters between the peak of each wave as is shown in this diagram. There is a universal speed that electromagnetic waves travel at which is 300m/s and this means that the wave frequency depends on the wavelength. The wave frequency for gamma rays is 300/0.03=10000hz. Gamma rays are produced by violent events in the universe such as supernovas and

today.Electric motors were made practical and affordable by Nikola Tesla and his induction motor. Before Tesla invented the induction motor was the dc motor that was impractical because it required two electric supplies for just one motor and expensive to make because it required rare materials on the other hand the induction motor needs but one power supply and can be made with inexpensive materials. The induction motor is powered by alternating current (AC) Tesla was one of the first to discover

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in
