Study Notes
Electromagnetic Waves
- Electromagnetic waves travel at a speed of approximately 299,792,458 meters per second in a vacuum.
- Electric and magnetic fields fluctuate in perpendicular planes to form an electromagnetic wave.
- In mechanical waves, a medium is required for propagation, whereas electromagnetic waves can propagate through a vacuum.
Characteristics of Electromagnetic Waves
- Electromagnetic waves exist within a wide range of frequencies, from very low frequencies (LF) to very high frequencies (gamma rays).
- Electromagnetic waves can exist in a vacuum, as well as in various mediums such as air, water, and solids.
