- Basic Concepts
- Frequency spectrum plots and classifies electromagnetic waves in space and environment
- Frequency is measured in hertz (Hz), representing complete wave cycles per second
- Spectrum ranges from 106 Hz to 1025 Hz, with radio waves at low end
- Applications
- Physicists use spectrum analysis to understand wave-matter interactions
- Health researchers monitor safety of X-rays and microwave technology
- Broadcasters identify frequencies prone to interference
- Light and Sound
- Different colors appear due to varying electromagnetic energy levels
- Sound waves can create different qualities through different frequencies
- White noise technique mixes sounds across spectrum for better sleep
- Broadcasting Regulations
- International Telecommunications Union allocates radio frequency bands
- FCC regulates US broadcast spectrum between businesses and public
- Different bands reserved for specific user groups to minimize interference
