Answer to Question #178626 in Physics for Jerick

Question

1. Before playing with the sim, discuss what you think will happen when you move the transmitter electron. 2. Remember from when we learned about electricity, when electrons move, they create a ELECTRIC field. Set the field display type to full field and the transmitter movement to oscillate. Describe what is happening. 3. Change the frequency and amplitude sliders and describe what happens to the fields.

4. Set the transmitter movement to oscillate, field display type to curve with vectors, and radiated fields. Describe what is happening in the transmitter and the receiver.

5. Click on Electron Positions to activate the wave graphs. Describe what is happening in the transmitter and the receiver.

Answer 1

1. I think the field will change
2. When electrons move, they create a magnetic field. Describe: the field vectors change their direction up and down but still point in the direction of the electron in both cases.
3. As I increase frequency, the length of the vectors increases. As I decrease the amplitude, the magnitude of vectors decreases.
4. The oscillations in the transmitter are greater in amplitude than in the receiver.
5. The graph moves at the same frequency but the amplitude is smaller for the receiver.
