- identify the physics principles contained within the following scenario. Explain how these principals connect to electricity, magnetism, or light in modern applications in physics. Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. For instance, Maxwell's research led to the development of radio waves. If you listen to a radio, then you are using Maxwell's research. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below. Mandy took a trip to Rome, Italy. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. She found a charging station with a USB adaptor port. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone's screen told her the phone was successfully charging. This USB port seemed to have very high amperage, meaning it…What is amperes's Law? Explain its Limitations And Application.Fill the blank spaces for the list of properties of the Electromagnetic waves given below: 1) EM waves are waves, where E,B & the wave direction are mutually to each other. 2) EM waves exert on the surface, when they impinge on it. 3) In the spectrum of electromagnetic waves, have the lowest frequency. 4) Of the seven different EM waves, + is needed for human vision.

Include a diagram of the EM wave that illustrates your answers and also include the direction of propagation (or the Poynting vector) for the EM wave in your diagram.Direction: Use the words below to complete the following sentences. Write your answer on a separate sheet of paper. A. Radio waves are produced through aerial in the form of is used (usually a radio or a television). The receiving aerial pick-ups the waves _5_ as the radio waves. which travel through the atmosphere. Another _3_ as and converts them into an alternating current with the same Alternating currents, aerial, receiver, transmitting, frequency B. Radio waves can experience Other broadcasts, tuned to a similar , caused by _8_ can also interfere. such as mountains. Interference, frequency, obstruction C. Radio waves cannot be are converted into , they 10 but when they reach a _11_ or 12 or 13 Receiver, heard, sound, pictures, seen D. Radio waves are good at get to listen to radio and TV broadcasts. TVs and radios can (sending out to lots of receivers) and that is how we _15_ broadcast signals using _14. antennas. Broadcasting, receiveWhat does it mean to say the light is polarized?

- Look at the door of a microwave oven. Describe the structure of the door. Why is there a metal grid on the door? How does the size of the holes in the grid compare with the wavelengths of microwaves used in microwave ovens? What is this wavelength?The electromagnetic spectrum ranges from cosmic rays to radio waves. Although we don't look at cosmic rays all too much in this unit, the order from highest to lowest energy in the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, mierowaves, and radio waves, For 3 sections of the EM spectrum, name 1-2 examples that can be used in our lives. We have provided an example down below. EM Spectrum Sections Examples Cosmic Rays Gamma Rays X-rays Ultraviolet Radiation Visible Light Our Sun Glowsticks Infrared Radiation Microwaves Radio Waves2. What is a Electromagnetic Wave? 3. Describe the LEFT side of the electromagnetic spectrum (Radio waves and Micro waves) to me.
