Electromagnetic Waves!
Different forms and how they're used
What Disturbances Create EM Waves?
Electromagnetic (EM) waves are produced by the vibrating of an electric charge. This causes them to have both an electric and magnetic component
Are EM Waves Different From Mechanical Waves?
Different Types of EM Waves
Radio: Has the longest wavelength, shortest frequency, lowest energy
Microwave: second shortest wavelength, second lowest frequency and energy
Infrared: third shortest wavelength, third lowest frequency and energy
Visible light: Is right in the middle in terms of wavelength, frequency, and energy
Ultra-violet: Third shortest wavelength, third fastest frequency and energy
X-ray: Second shortest wavelength, second fastest frequency and energy
Gamma Ray: Has the highest frequency, shortest wavelength, most energy
What Are They Used For?
Radio Waves
Radios capture radio waves emitted by radio stations, allowing you to listen to music
Micro-waves
Microwaves use micro radiation to cook food. Micro-waves can also be used by astronomers to learn about nearby galaxies.
Infrared Waves
Night vision goggles function by picking up the infrared light emitted by skin and other objects with heat. Infrared waves also help with mapping the dust and spaces between stars
Visible Light
Ultra-Violet
Ultraviolet light is responsible for the tanning and burning of skin. It is also emitted by hot objects in space
X-Ray
Gamma Rays
Gamma ray imaging can see inside your body. The universe is the largest gamma ray emitter
