The Electromagnetic Spectrum

All devices have electromagnetic waves; radios and microwaves are all examples. These devices are also part of the electromagnetic spectrum. Electromagnetic waves can also travel through a vacuum. This means they do not require a medium. Since these waves can travel in space their speed is referred to as the speed of light. The speed of light is 300,000 km/s. As of right now nothing can travel faster than the speed of light. The spectrum also has tiny masses of radiation called photons and there is also potential energy. The electromagnetic spectrum is divided into six parts. They are radio waves, microwaves, infrared waves, visible light, uv rays, x-rays, and gamma rays. The spectrum is a model that shows the range all visible and invisible electromagnetic waves. The spectrum has a wavelength and a frequency. At the beginning of the spectrum it has the longest wavelength but with a lowest frequency. At the end of the spectrum it has the shortest wavelength but highest frequency. All around us there are radio waves. If we look closely we still cannot see them because the waves are converted to sound waves. Microwaves are also radio waves. Microwaves vibrate the electromagnetic field to cause friction, which causes heat, and so it heats up the water molecules to cook. Microwaves have a wavelength less than 30cm. An infrared wave is heat that was transmitted to us by infrared waves. For example hotter objects have more infrared than cooler ones. The color for infrared is red, orange, and

Essay on Electro: Radiation Electromagnetic Radiation

White light can be split up into a spectrum of many different colours and visible light is just part of a continuous spectrum of electromagnetic radiation. Different types of electromagnetic radiation have different hazards and uses. What is a spectrum? The visible spectrum a rainbow appears to come out of the prism Using a prism, you can split up white light to form a spectrum. (A prism is a block of glass with a triangular cross-section.) The light waves are refracted as they enter and leave the…

Effects Of Electromagnetic Radiation

Introduction Electromagnetic radiation, generally known as light, is energy composed of electric and magnetic field components. It also displays wavelike properties such as refraction, reflection, diffraction, and interference. Electromagnetic waves can be found in different forms, these include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x-rays, and gamma rays. “Despite the fact that all these electromagnetic waves travel at the same speed, they differ in…

frequency. When the waves are long the frequency is small and when the waves are short the frequency is high. Electromagnetic radiation interacts with matter in the visible light spectrum because if we didn’t have the radiation reacting with the matter, we would just see in black, white, and…

Electromagnetic Radiation and Electron Essay

Nietkalieva Dinara IS113k Lab 1: Radio and Light Waves Virtual Lab 1) How is the radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter, electrons oscillate up and down and are thus accelerating. An electron will exert a force on another…

Essay on Advertising: Electromagnetic Radiation and Nsa

The software which the NSA has developed uses a highly classified technology which uses Radio Waves to enter, access, alter and control the victims computer. The news reports say that NSA has been using this technology called 'Quantum', since 2008 and the technology uses a covert channel of radio waves to communicate with the victims computer. Using the covert radio channel frequency negates the requirement of internet, so the NSA has control over internet enabled as well as non internet PCs real…

Electromagnetic Radiation and Concentration Curve Essay examples

The purpose of this lab is to evaluate light absorption in a variety of solutions to identify an unknown solution’s concentration by using a spectrophotometer to measure a particular substances absorption of radiation at a precise wavelength in the visible region of the spectrum to construct a concentration curve. This was then compared to the peak of absorbance of the unknown to determine the concentration of the unknown substance (Kotz, 2014). Spectroscopy is the study of light, which can be thought…

Electromagnetic spectrum Essay

Electromagnetic spectrum The electromagnetic spectrum is made of different types of electromagnetic radiation. White light is able to be separated in a spectrum of many various colours, where visible light is a part of continuous spectrum of electromagnetic radiation. All types of various electromagnetic waves are moving at same speed in space.( BBC News, 2015) Figure (1) the light is refracted by ( BBC News, 2015) Different types of radiation There are different types of electromagnetic radiation…

How Does Microwave Radiation Destroy Yeast

Does Microwave radiation destroy yeast or plants more efficiently? Higher radiation levels can affect a plant or an animal or any living thing harmfully. Microwave radiation is classified as non-ionizing and a GHz. Electromagnetic radiation that doesn’t transfer enough energy per quantum to ionize atoms or molecules is known as non-ionizing radiation. Yeasts are single celled, eukaryotic microorganisms in the fungus kingdom. Plants are mainly photosynthetic, multicellular eukaryotes classified…
