The second part is a containment field of directed EM sphere‚ followed by an EM tube‚ which funnels the soul into a special sphere; it contains most forms of radiation‚ keeping the soul alive in a new vessel‚ but leaves them incapable of anything but a

LABORATORY ACTIVITY FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will

right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different because sound and ultrasound are vibrations in the air‚ while radio waves are electromagnetic waves that can travel in a vacuum. UltraSound: Basic Idea – Send waves into body which are reflected at the interfaces between tissue – Return time of the waves tells us of the depth of the reflecting surface SoundWaves. Sound wave propagate

several countries over many decades.. The first practical demonstrations of television‚ however‚ were developed using electromechanical methods to scan‚ transmit‚ and reproduce an image. The television works by receiving wireless transmitted electromagnetic waves and changing them into sound and light energy that is used for viewing television. The beginning of the television is littered with a series of devices that were very effective at getting wireless electronic patterns that contained light

have MRIs done than their poorer counterparts should be examined and should be the issue. 2.) The differences in energy between these lines is produced by electrons going from high to lowe energy orbits and as a result releasing energy and electromagnetic waves with longer wavelengths. This means that these lines are lower in energy when compared to the ultraviolet line spectrum. In addition‚ the ultraviolet lines indicates that electrons is going from high to low energy thus‚ releasing more energy

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

treatment with radiation I am for the use of radiation because it can be used in many good ways. My sub group is medicine. I am researching a radiation treatment used for helping cancer patients. This is a good use of radiation because it kills the cancer cells and may even cure the cancer. It doesn’t always cure it but it will slow the process down. One reason radiation therapy is used‚ is to destroy the cancer cells. It is also for shrinking tumors. Tumors are mostly cured by the radiation. It can also

1901. He later filed a patent for the Apparatus for the Utilization of Radiant Energy. This basically was a Photoelectric alternating current stepping motor. Heinrich Hertz observed the photoelectric effect and the production and reception of electromagnetic waves. His receiver consisted of a coil with a spark gap‚ where a spark would be seen upon detection of EM waves. He used this device to study the photoelectric effect. In today ’s society‚ photocells are widely used. They are within many electronic
