Introduction
I have found some material about Electromagnetic waves. I believe this material will give a little insight on what is taught in Universities, and there's also a material that I believe is an Exam paper. It's pretty interesting to compare what do people in other countries study in physics.
Task
Here are some questions that need to be answered:
- What are waves?
- What are the types of waves?
- What is light?
- What is amplitude?
- What is the propagation velocity of a periodic wave?
- What creates a magnetic field?
- What is the main difference between AM and FM waves?
- How can you describe the speed of an electromagnetic wave in the vacuum?
- What do electromagnetic waves carry?
- What is the speed of electromagnetic waves in a material medium?
Process
Answers to these questions you can find in sources below:
- [video:https://youtu.be/SPvi1AyShzw width:512 height:288]
- Ohio State University lecture notes
- CBSEN Exam notes
Evaluation
Good job! You can compare your answers to the right answers down below:
|
1. |
Transfer of energy from place to place without transferring mass |
| 2. | Transverse and longitudinal |
| 3. | An electromagnetic wave |
| 4. | Maximum excursion of a particle of the medium from the particles undisturbed position |
| 5. | V=λ/T |
| 6. | The current used to generate the electric wave |
| 7. | AM waves are longer and tend to bend easier than FM waves |
| 8. | It is related to the free space permeability and permittivity |
| 9. | Energy |
| 10. | v =1/(SQRT)(με) |
Conclusion
You did it! Congratulations! I hope this wasn't boring and you gained some knowledge thanks to these materials.
