Study Notes
Electromagnetic Waves
- Electromagnetic waves are generated by the acceleration of charged particles, such as electrons.
- The direction of wave propagation in an electromagnetic wave is perpendicular to the electric and magnetic field vectors.
Characteristics of Electromagnetic Waves
- The form of electromagnetic waves with the broadest frequency range is gamma rays.
- If the wavelength of an electromagnetic wave increases, its frequency decreases.
- The speed of an electromagnetic wave in a vacuum is approximately 3.0 x 10^8 meters per second.
History of Electromagnetic Waves
- James Clerk Maxwell played a role in developing equations that demonstrated the connection between electricity and magnetism.
Types of Electromagnetic Waves
- Visible light is NOT a type of electromagnetic wave (it is a part of the electromagnetic spectrum).
- The primary distinction between a radio wave and a light wave is their frequency, with radio waves having a lower frequency.
- Radio waves are predominantly used in communication.
- Radio waves result from making electrons vibrate in an antenna.
Applications of Electromagnetic Waves
- Energy transformation from electromagnetic waves to electrical signals occurs at the receiving station in communication.
- Satellite Communication is an application of radio waves.
- FM stations are broadcast using Very High Frequency (VHF) radio waves.
- Gamma rays are employed in the sterilization of medical equipment.
- Photosynthesis, the process by which green plants make food, utilizes visible light.
- The narrow beam of light concentrating effects on the retina, causing a blind spot, is an effect caused by visible light.
