PHY112 – Laboratory 9 – Worksheet
•When you visit the simulation you will have a decision to possibly run the simulation or download the simulation. Work may not work with all personal computers. If it does not run, down load the simulation and job from there. •When the simulation opens, play with the regulates and keys to become knowledgeable about how the simulation works. •Note: A formal lab report is not required with this activity. You may cut and paste this kind of worksheet to a new Term document and adjust the spacing to suit your needs. Methods
•Open the simulation.
•Explain the way the radiating electrical field (or electromagnetic signal) is created when radio stations broadcast. A radio wave (radiating electric power field) advances out from the origin, traveling with the speed of light. The original source, for example an antenna, creates oscillating electric(E)/ magnetic(B) fields. These domains are perpendicular not only to each other but to the direction of the traveling wave, and travelling away from the antenna. The electromagnetic wave is definitely, therefore , a transverse wave. The electric/ magnetic domains store the power of the influx. Basically, the oscillating current to the antennas sets the electrons in motion. These electrons, staying accelerated, create discontinuity inside the electromagnetic field. •Briefly make clear what is actually producing radio stations signal. Energy, in the form of electromagnetic radiation, applies steadily oscillating force on charges (electrons). The push is originally exerted highly in one way, but then reverses for the cycle to keep. The radio waves push within the electrons in the metal in the antenna, triggering the varying up and down the length of the source (antenna). The current are these claims created in the antenna. •Adjust the transmission device on the sim so that it is in the sinusoidal mode and the electrons are oscillating up and down by a regular frequency. Ensure the " screen the curve” and the " radiated field” boxes are checked. What really does the curve...
