I want to understand what actually happens when some data is sent over a particular frequency/channel. My understanding is that to send data on a particular channel, a ripple is created in the medium with the corresponding frequency. Not sure how the receiver accepts the info from the channel.
In: Technology
Think of morse code. its just a light blinking on and off. the frequency/color of the light is the channel. If you arent looking when the message is sent, it is lost.
to get a different channel you just use a colored filter to only see a specific channel.
same for wireless, its just the light is a frequency you cant see that thinks most materials are transparent, and the filter is electronic, and its not morse code, its binary code.
there is no medium, light doesnt need one.
