Explain how light travels through a fiber-optic cable, using the terms "reflection" and "total internal reflection".
2.
Why does the light signal have to be regenerated in a fiber optic system?
3.
How can ones and zeros be encoded in a light signal?
4.
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!)
5.
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.

During _________________ the energy of a light wave is transferred to and heats up an object.
8.
During ______________ the energy of a light wave bounces off an object.
9.
______________ is when light traveling in one medium passes into another and bends at the intersection of the two materials.

11.
The minimum angle for total internal reflection is called the ______________.
12.
An added advantage of using light in for data transmission is that the fiber can carry multiple signals using different light ____________.
