What is electromagnetic radiation?]]> 2017-05-31 12:39:19 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/174606873 benjamin_safford https://padlet.com/benjamin_safford/irhm9iou7oht/wish/175468808 "Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths."]]> 2017-06-06 22:16:07 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/175468808 benjamin_safford https://padlet.com/benjamin_safford/irhm9iou7oht/wish/175469774 If wifi were to have no EM, this is what it would look like. How does Wifi even exist? Hedy Lamarr, the inventor of radio waves made it possible to create radio wave guided torpedoes. Australian John O Sullivan is the inventor of wifi and made it fast and possible. He is working on SKA, which spreads radio waves all over the globe!]]> 2017-06-06 22:30:12 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/175469774 benjamin_safford https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177132574 A wifi router is one of the many powerful household objects. It looks like a box with antennas.
But it runs most of the apps on devices such as phones and laptops. The average range for a 802.11b/g router goes up to 150 feet. 802.11/g contain twice the range!]]> 2017-06-21 19:28:06 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177132574 benjamin_safford https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177133776 www.speedguide.net/faq/what-is-the-typical-range-of-a-wireless-lan-330

For example, internet is provided when you want to play Roblox and saves that game for you. Wifi will allow you to play the game when connection is provided. So if you like Roblox, thank internet.]]> 2017-06-21 19:54:00 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177134104 benjamin_safford https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177137506 drive.google.com/file/d/0Bxoj7XfP2jhbeEhzYWpLTkJIQTA/view]]> 2017-06-21 20:44:56 UTC https://padlet.com/benjamin_safford/irhm9iou7oht/wish/177137506
