Explain how light travels through a fiber-optic cable, using the terms "reflection" and "total internal reflection".
Why does the light signal have to be regenerated in a fiber optic system?
How can ones and zeros be encoded in a light signal?
Nanette talks about how every technological system is like a puzzle, that all of its pieces must fit - and work - together properly. Describe how this applies to at least two other technological systems you've studied. (Think back to previous chapters!)
Nanette is a test engineer. Why is testing a critical part of the development process? Describe how at least two other engineers you've learned about test technologies they've designed.
___________ is anything that interferes with the clarity of a message/
During _________________ the energy of a light wave is transferred to and heats up an object.
During ______________ the energy of a light wave bounces off an object.
______________ is when light traveling in one medium passes into another and bends at the intersection of the two materials.
Refraction occurs because the _____________ in one material is different than the _______________ in the second. (Same word(s).)
The minimum angle for total internal reflection is called the ______________.
An added advantage of using light in for data transmission is that the fiber can carry multiple signals using different light ____________.
