The Power of Light: How Electromagnetic Radiation Makes Communication Possible

Overview

Light itself doesn't carry information. 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.
