Electromagnetic radiation

Medicine Changed by Radiation Radiation has changed over the years and wasn’t even known to be used in medicine until after it was used in the military in World War II. It was discovered by a German scientist but then the possibilities of all the things it could be used for was discovered by a Polish-born French scientist. Radiation changed medicine for the better by killing off cancerous, disease ridden germs and cells, this is significant because it changed the way we look at treatment. In…

energy. There are many different forms of kinetic energies like sound, motion, thermal energy, electrical energy. Nevertheless, there would be no life on Earth without radiant energy. What is radiant energy? The energy of electromagnetic waves and gravitational radiation is radiant energy. Radiant energy is the result of a change in configuration of electrons. It can travel through any substance including air, liquid, glass, and space. However, matter is not necessary for transmission of…

realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy embodied in oscillating electric and magnetic fields Amplitude- (of a wave) is the vertical height of a crest. The amplitude of the electric and magnetic field waves in light determines the light’s intensity or…

Most people know that heat moves from hot objects to cold objects, but do they know how that heat is transferred? There are only three ways that heat can be transferred: conduction, convection, and radiation. Today I will endeavor to inform the reader on how these three different methods of heat transfer work and provide examples of where they occur in the real world. The most prevalent, and most commonly recognized, form of heat transfer is conduction. Conduction is the transfer of heat…

reasons. One it can damage DNA and gene expression cells, it can also disturb pacemaker functionality, and it can expose the brain to two times the average radiation. Cell phones are not safe because it can change DNA and gene expression cells, it can disturb functioning of pacemaker, and can expose the brain to two times the average radiation. One reason cell phones are not safe because it can damage DNA and change gene expression cells. The source is the 2012 Journal of Neuro Oncology. The…

increase food production. Although pests have numerous benefits they also have few drawbacks such as possible toxicity to humans and other species. What is light? Light is the electromagnetic radiation which is responsible for the sense of vision and sight. This electromagnetic radiation is a portion of the electromagnetic spectrum. Primary properties of visible light are intensity, propagation direction,…

the pin on the device, in a spilt second after the two masses collide creating an uncontrolled chain reaction as the masses once together become a supercritical mass, the explosion releases energy in the form of a blast wave, thermal radiation, and nuclear radiation. A tremendous amount of energy released in a nuclear detonation, temper­atures of tens of millions of degrees develop in the immediate area. At these temperatures, everything near ground-zero vaporizes. The remaining gasses of the…

New technologies and materials have appeared with the development of the industrial and post-industrial society that make human life more convenient, without them it is impossible to imagine the life of the modern person. However, it is still difficult to answer the question whether all technology is safe for humanity? One of the most urgent and discussed issues is the problem of cancer caused by cell phones. Scientists from all over the world are trying to find the answer to this question by…

capacitor, the coil, and electrodes. Early radio antennas and telegraphs used his Coils. They use electromagnetic resonance, which is produced by applying steady magnetic field and electromagnetic radiation (usually radio waves) to a sample of electrons and then adjusting both the strength of the magnetic field and the frequency of the radiation to produce absorption of the radiation("Electromagnetic Resonance - Springer." http://link.springer.com/10.1007%2F978-0-387-73003-5_431.

things was just a thing everyone dreamed about. It was a mystery what would it look like if you can see through things like the human body. Now you can because of X-ray! Ever wonder how does X-ray works though? It works by Electromagnetic Waves and its a type of Electromagnetic Waves. X-rays are very useful to society. We use waves a lot. Though there is pros and cons from X-ray. Aren’t X-rays very interesting? X-rays are very useful to society. They help with a lot of special things! X-rays…
