Effects of Computer Radiation in the Health of I-BSN-2 Students of Cavite State University I. Introduction Nowadays‚ computers are very common in a household. Computers are very advantageous which actually has unlimited capabilities; in seeking a certain information‚ for recreation‚ for entertainment purposes and many other uses. But despite those infinite uses of computers‚ some say that computers cause detrimental effects to those who are exposed to its radiation. Radiation‚ in

NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

Introduction Thin Film Interference When plane electromagnetic wave of wavelength λ is incident on a dielectric surface‚ part of the electromagnetic wave is reflected‚ and part of it is transmitted. If the dielectric is thin‚ i.e. its thickness t is comparable to λ‚ the plane electromagnetic wave will be reflected again at the second dielectric surface‚ as shown in Figure 1. [pic] Figure 1. Electromagnetic waves incident at angle θ1 reflected from the top and bottom surfaces

An adventure into Astronomy Late at night I like to go into my backyard with a telescope and look at the stars that far away in the night sky. The view of thousands of stars feeds me with wonder and amazement about both the stars origins‚ and what treasures they may hold floating around them. All life needs a host star to form around‚ and all life comes from the ashes of these once glorious masses of gas. Astronomy offers us a great view of the universe around us‚ you can join me and others‚

Premium Light Radio Electromagnetic radiation
Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated their speed of propagation. This development‚ along with the experimental work of Heinrich Hertz starting in 1887‚ showed conclusively that light is indeed an electromagnetic wave. The wave picture of light is not the whole story‚ however. Several effects associated with emission and absorption of light reveal a particle

energy transformation is a change in the type of energy‚ for example a change from sound energy to electromagnetic waves. Relating this to the mobile telephone‚ it undergoes basic energy transformations of‚ sound wave (your voice)‚ to electrical energy (in the wires inside the phone)‚ to electromagnetic waves (from the phone to the tower)‚ to electrical energy (at the tower)‚ then to electromagnetic waves (to reach the receiving phone)‚ then electrical energy (inside the receiving phone)‚ then to
