1. Electromagnetic Spectrum
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It includes visible light, radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays.
Electromagnetic waves are produced by the vibration of electric and magnetic fields. The frequency of an electromagnetic wave is determined by the rate at which the fields vibrate. The wavelength of an electromagnetic wave is determined by the distance between two consecutive peaks of the wave.
Types of Electromagnetic Waves, Electromagnetic spectrum webquest answer key
- Radio waves have the lowest frequency and the longest wavelength. They are used for communication, navigation, and remote control.
- Microwaves have a higher frequency and a shorter wavelength than radio waves. They are used for cooking, heating, and communication.
- Infrared radiation has a higher frequency and a shorter wavelength than microwaves. It is used for heating, night vision, and remote sensing.
- Visible light has a higher frequency and a shorter wavelength than infrared radiation. It is the light that we can see.
- Ultraviolet radiation has a higher frequency and a shorter wavelength than visible light. It is used for tanning, sterilization, and phototherapy.
- X-rays have a higher frequency and a shorter wavelength than ultraviolet radiation. They are used for medical imaging and security screening.
- Gamma rays have the highest frequency and the shortest wavelength. They are used for cancer treatment, sterilization, and research.
