Understanding Electromagnetic Waves
Electromagnetic waves are a form of energy that travels through space in the form of oscillating electric and magnetic fields. These waves are produced by accelerating charged particles and can propagate through a vacuum or a medium. The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second, which is the speed of light.
Electromagnetic waves are classified based on their frequency and wavelength. The electromagnetic spectrum encompasses a wide range of waves, from radio waves to gamma rays. The following table provides a brief overview of the different types of electromagnetic waves and their corresponding frequency and wavelength ranges:
| Electromagnetic Wave | Frequency Range (Hz) | Wavelength Range (m) |
|---|---|---|
| Radio Waves | 3 x 10^11 – 3 x 10^14 | 1 mm – 100 km |
| Microwaves | 3 x 10^14 – 3 x 10^16 | 1 mm – 1 m |
| Infrared | 3 x 10^16 – 4.3 x 10^14 | 700 nm – 1 mm |
| Visible Light | 4.3 x 10^14 – 7.5 x 10^14 | 400 nm – 700 nm |
| Ultraviolet | 7.5 x 10^14 – 3 x 10^16 | 10 nm – 400 nm |
| X-rays | 3 x 10^16 – 3 x 10^19 | 0.01 nm – 10 nm |
| Gamma Rays | 3 x 10^19 – 10^25 | 0.001 nm – 0.01 nm |
