Electromagnetic Waves

1. Color of wave(frequency, wavelength) {Electromagnetic spectrum): Violet(highest frequency, shortest wavelength), Indigo, Blue, Green, Yellow, Orange, Red(lowest frequency, longest wavelength)

2. Uses of electromagnetic waves: 1. Gamma rays(radiation therapy and cancer treatment) 2. X-rays(medical and everyday applications) 3. Ultraviolet(sunbeds and sterilization of medical equipment) 4. Visible light(optical fibers) 5. Infrared(remote controllers and ear thermometers) 6. Microwaves(ovens and satellites) 7. Radio waves(radio and telecommunications)

3. Effects of electromagnetic waves: 1. Infrared heating 2. Ionization and the effects of ionizing radiation on living matter
