It's the way we manipulate this light that allows us to communicate. Communication technologies encode information onto the light wave. There are two main methods: Amplitude Modulation (AM): This method varies the intensity (amplitude) of the light wave to represent information. Imagine a flickering light bulb - a bright flash could represent a 1, while a dim flicker could represent a 0. This method is used in some older radio transmissions. Frequency Modulation (FM): Here, the frequency (number of cycles per second) of the light wave is varied to represent information. Think of a police siren - a high-pitched whine could represent a 1, while a lower-pitched wail could represent a 0. FM is more resistant to interference and is used in many modern radio transmissions.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Herlie\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3384283171\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783384283177\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Tredition Gmbh\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/08\/2024\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 100\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.35lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.24d","brand":"Herlie","offers":[{"title":"Paperback","offer_id":48659543818495,"sku":"9783384283177","price":16.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/the-power-of-light-herlie-9783384283177","provider":"WR Book House","version":"1.0","type":"link"}
