Electromagnetic spectrum

The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers

Gamma rays are the most interesting wave in the electromagnetic spectrum. In 1900, Paul Villard discovered Gamma rays unexpectedly while he was conducting a radioactivity experiment (ARPANSA). He differentiated gamma rays from x-rays because he realized that gamma rays had a greater penetration power depth through his further study and research (ARPANSA). Gamma radiation studies revealed that they are very dangerous, but scientist also found a way to protect against gamma radiation and many beneficial

animals to RF almost continuously--up to 22 hours a day--and to whole-body radiation, unlike people's head-only exposure (Phones, Cancers and Brain Tumors - What is the REAL story). Controversially, some types of cancer are being cured with electromagnetic waves. Research conducted at the MD Anderson Cancer Center in Houston shows that spiking

How does UV radiation affect prokaryotic and eukaryotic cells? In this experiment, saccharomyces cerevisiae, a type of yeast, and the K-12 strain of E.coli will be exposed to UV radiation. In order to conduct this experiment, one must understand what yeast, saccharomyces cerevisiae, E.coli, and UV radiation are, and how UV radiation affects a cell. This report introduces yeast then goes over the description, importance, and structure of saccharomyces cerevisiae, a certain species of yeast, and E

Ultraviolet light, also known as UV light, is a type of electromagnetic radiation. Ultraviolet light comes from the sun and is invisible to the human eye. Although humans are constantly exposed to UV light, too much ultraviolet radiation could be potentially harmful to living tissue. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies (Lucas 2015). This range is known as the electromagnetic spectrum which is split into

X-rays This is a scientific report on x-rays, it’s history, uses, implications and other relevant facts. More relevance will be given to its medical uses/ importance as it was the most beneficial trait that x-rays brought. X-rays were discovered in 1895 when Wilhelm Conrad Röentgen was doing some experiments with electron beams in a gas discharge tube and observed a glow in one of his fluorescent screens whenever the electron beam was on. It was a fact that fluorescent material usually glowed

X-rays may be invisible waves found on the electromagnetic spectrum which can almost make their known danger seem of little importance because our five senses cannot measure their activity, however x-rays must not be taken lightly. Radiologic Technologist must keep in mind the dangers and gravity of the force that they are working with on a daily basis. Patients should have the right to their own safety when undergoing a medical procedure that requires the use of x-rays. Radiologic Technologist are

Plant water stress is a major factor affecting crop yield. With the ever-increasing human population, there is a constant stress exerted on water resources (McGwire et al., 2000). So irrigation to avoid or relieve this stress must be done judiciously, not only to avoid environmental problems such as groundwater pollution and runoff, but also to keep the cost down on a limited and expensive resource. Soil moisture sensors are often used for precision irrigation control purposes. However, soil moisture

9. Introduction: Plant water stress is a major factor affecting crop yield. With the ever-increasing human population, there is a constant stress exerted on water resources (McGwire et al., 2000). So irrigation to avoid or relieve this stress must be done judiciously, not only to avoid environmental problems such as groundwater pollution and runoff, but also to keep the cost down on a limited and expensive resource. Soil moisture sensors are often used for precision irrigation control purposes. However

and Microstrip feeding technique will be discussed further through this chapter. Antennas are key components of any wireless communication system and it is a device that provides a way for radiation or receiving electromagnetic waves. IEEE standard definitions for antenna (IEEE Std 145-1983) defines antenna as a means for radiating or receiving radio wave. Figure 3.1 shows an antenna as transition device. The arrows displayed in Figure 3.1 shows the electric field lines
