Waves Inv. 4 - Communication Waves.

____ means it has to do with _____ waves.

Optical fibers ____ ___ for very ___ distances by using total internal reflection. The information is encoded as ____. Light waves travel ____ ___. Information sent from New York by fiber optics could reach Australia in less than ___ ____.

The information must be encoded to be sent as patterns of ______.

But Morse code serves as a ____ that we can use to understand ___ ___ is __ and ___ through optical fibers as light waves.

Answer:

In modern communications, such as Internet, cable TV, and telephone communications, information is sent via signals in laser light through clear cables called optical fibers, which are also known as fiber optics. Optical means it has to do with light waves.

The information must be encoded to be sent as patterns of light. One model of how information can be encoded is Morse code. Actual Internet data, cellular phone, and TV signals are not sent by Morse code. But Morse code serves as a model that we can use to understand how information is encoded and sent through optical fibers as light waves.

The information must be encoded to be sent as patterns of light. One model of how information can be encoded is Morse code. Actual Internet data, cellular phone, and TV signals are not sent by Morse code. But Morse code serves as a model that we can use to understand how information is encoded and sent through optical fibers as light waves.

Optical fibers carry information for very long distances by using total internal reflection. The information is encoded as light. We will learn more later about how this code is created and used. Light waves travel very fast. Information sent from New York by fiber optics could reach Australia in less than 1/10 second.
