order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each phase of light that can be detected by all organisms‚ not just humans. Light and matter have a perfect relationship in which matter emits and absorbs light

Hodgkin’s lymphoma was brung to my attention by a pair of football players that were diagnosed with the disease‚ Kansas City Chiefs elite safety Eric Berry and University of Pittsburgh star running back James Conner. Hodgkin’s lymphoma‚ also known as Hodgkin’s disease‚ is a cancer in part of the immune system‚ and as the cancer progresses‚ it makes it gradually more difficult for the body to fight it. Both of the players afore mentioned have fully recovered from Hodgkin’s lymphoma and are back on

life is a very special gift. My grandfather was a victim of cancer and he‚ despite all of the suffering he endured‚ wanted to stay alive for as long as he could. He wanted to remain a strong influence on how is family viewed life. Through the radiation treatments and constants visits to doctors he never gave up on his life. I can remember him saying “Baby I’m sick but I’m here with you and it makes the pain seem a bit more bearable.” Through this I learned never to give up on life even when it

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
Premium Electromagnetic radiation Wavelength Infrared
wavelength — the distance between the crests of the waves — or its frequency — the number of crests that pass by in a given amount of time.The higher the energy of the radiation‚ the shorter its wavelength and the higher its frequency will be. Blue light‚ for example‚ has a higher energy and therefore a higher frequency and shorter wavelength than red light Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours

EMC shielding is a protection provided to electrical and electronic devices to protect them from EMI. EMI refers to the phenomenon where electromagnetic radiation affects the performance of electrical and electronic equipment. EMC shielding is used across many industries because of its capability to effectively neutralize the effects of EMI. Covered in this Report0280035The report covers the present scenario

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

Laser-(light amplification by stimulated emission of radiation) used to provide the high-powered‚ tightly controlled light wavelengths necessary for high-speed‚ long-distance optical fiber transmission. 4. Output Pattern-is the energy couples into the core of the optical fiber. 5. Output Power- allows transmission
