Electromagnetic Waves
All the facts and science behind EM waves you should know!
The Differences in EM waves and Mechanical Waves
What disturbances can create an EM wave?
Types of Electromagnetic Waves
Radio
Frequency: > 1 x 10-1
Wavelength: < 3 x 109
Energy: < 2 x 10-24
Scientists use radio telescopes to view many things in space. Also, a more dily use of radio waves would be to transmit sound in radios.
Microwave
Frequency: 3 x 109 - 3 x 1011
Wavelength: 1 x 10-3 - 1 x 10-1
Energy: 2 x 10-24- 2 x 10-22
A daily use for a microwave wave, would be in a microwave because of this waves ability to vibrate and create heat from it. The most needed thing nowadays is WIFI, it makes our phones work, which are a huge part of our lives. In fact, WIFI needs microwave waves to work.
Infrared
Frequency: 7 x 10-7 - 1 x 10-3
Wavelength: 3 x 1011 - 4 x 1014
Energy: 2 x 10-22 - 3 x 10-19
The remote of your very television uses infrared waves to allow you to channel surf by emitting a infrared signal to the TV. Infrared lamps are what heat a room or keep food warm and these inventions also use infrared lamps. The heat from the waves allows heated energy to come out to warm whatever it is warming.
Visible Light
Frequency: 3.9x1014 - 7.9x1014
Wavelength: 3.8x10-7 - 7.6x10-7
Energy: 0.3 - 0.5
Fireflies, the little bug that emitts a neon yellow color ever so often on warm sunny nights. Even these little creatures are an example of visible light because you can see it. Lightbulbs as well because the light coming out of it is visible.
Ultra Violent Light
Frequency: 7.5 x 1014 - 3 x 1016
Wavelength: 1 x 10-8 - 4 x 10-7
Energy: 5 x 10-19 - 2 x 10-17
Do you ever wonder why you get a tan in the warm summer days? Well, you can thank ultra violet rays for this. Also, the sun can produce these waves that are near visible to the naked human eye.
X-Ray
Frequency: 3 x 1016 - 3 x 1019
Wavelength: 1 x 10-11 - 1 x 10-8
Energy: 2 x 10-17 - 2 x 10-14
The dentist and airport security are two great examples of X-ray because they are both scanning through either your mouth or your bag to check if everything is okay!
Gamma Ray
Frequency: < 1 x 10-11
Wavelength: > 3 x 1019
Energy: > 2 x 10-14
Doctors use gamma rays to see inside of you when they want to check up on your body. Although, there are many uses of gamma rays and producers, the universe itself is the largest because of its production of gamma rays.
