Properties of Electromagnetic Waves
Electromagnetic waves have a number of fundamental properties, including their speed, wavelength, and frequency.
The speed of electromagnetic waves is the same in all inertial frames of reference, and is equal to the speed of light, approximately 299,792,458 meters per second (186,282 miles per second).
The wavelength of an electromagnetic wave is the distance between two consecutive peaks or troughs of the wave. The wavelength is inversely proportional to the frequency of the wave, meaning that waves with higher frequencies have shorter wavelengths.
The frequency of an electromagnetic wave is the number of peaks or troughs that pass a given point in one second. The frequency is directly proportional to the energy of the wave, meaning that waves with higher frequencies have higher energies.
These properties of electromagnetic waves affect their behavior and applications. For example, the speed of electromagnetic waves makes them ideal for use in communication, as they can be used to transmit information over long distances quickly and efficiently. The wavelength of electromagnetic waves determines their ability to penetrate different materials, making them useful for a variety of applications, such as medical imaging and security.
Electromagnetic Spectrum
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It is divided into seven regions, each with its own unique properties and applications.
The following table summarizes the different regions of the electromagnetic spectrum, their frequencies, and their uses:
| Region of the Electromagnetic Spectrum | Frequency Range | Wavelength Range | Uses |
