一、First of all,the use of mobile phone is harmful to health.Electromagnetic waves alter [electric activity of the brain] and cause disturbance in sleep 1.It also causes difficulty in concentration,fatigue,and headache [2]; and increase reaction time in a time-dependent manner [3].They incr...
The magnet then creates a strong magnetic field that aligns the protons of hydrogen atoms. These hydrogen atoms come from the human body, which is 50-65% H2O. These atoms are exposed to a beam of radio waves. This spins the various protons of the body. As they spin, they produce a ...

Radio waves10–1,0003 × 105–3 × 107 Table 1. Frequency and wavelength domain of electromagnetic radiations The decomposition of electromagnetic radiation into its component wavelengths is fundamental to spectroscopy. Evolving from the first crude prism spectrographs that separated white light into it...
This process begins with light from an incandescent illumination source passing through a polarizing filter placed between the light source and the condenser. This orients the light waves in one direction so the electromagnetic waves oscillate in only one plane. ...
Radiant energy basically encompasses all energy that is found in electromagnetic waves.Advantages of radiant energyinclude: it is relatively cheap to set up and it is easy to use on a small scale. The main disadvantage of radiant energy is not efficient for large amounts of energy. ...
transmit data over air. Means that, no expensive copper cabling is required and data is transferred over air. Wireless networks use Radio waves to communicate, instead ofcopper twisted pair cables. Radio waves are electromagnetic waves having wavelengths longer than infrared in electromagnetic spectrum...
While there are several strong advantages of induction lights, it’s best to look at the disadvantages before making the decision and pulling the trigger. So here are the cons… Induction lamps are bulkier than other lamps Due to the electromagnetic inductor needing to wrap around the bulb, t...
These tags rely on the electromagnetic field that is generated by specific RFID tag readers to create enough electrical charge to transmit the stored data in radio waves (Venkateswara, 2011). 1120 Words 5 Pages 7 Works Cited Good Essays Read More Ec 544 Week 3 Case Study Essay Some of the...
