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.

___________ is anything that interferes with the clarity of a message/
Explanation
Noise refers to anything that disrupts the clarity of a message. It can be a single noise or multiple noises that hinder effective communication. These noises can be external, such as background sounds or distractions, or internal, such as personal thoughts or biases. Regardless of the form, noise acts as a barrier to understanding and can prevent the intended message from being accurately received and interpreted.Rate this question:

During _________________ the energy of a light wave is transferred to and heats up an object.
Explanation
During absorption, the energy of a light wave is transferred to and heats up an object. This occurs when the object absorbs the light wave and converts its energy into heat. Absorbtion is not a correct spelling and does not have a specific meaning in this context.Rate this question:

During ______________ the energy of a light wave bounces off an object.
Explanation
During reflection, the energy of a light wave bounces off an object. This phenomenon occurs when light waves encounter a surface and are redirected back into the same medium. The angle of incidence, which is the angle at which the light wave strikes the surface, is equal to the angle of reflection, the angle at which the light wave bounces off the surface. This process allows us to see objects as they reflect light into our eyes, enabling vision and perception of our surroundings.Rate this question:

______________ is when light traveling in one medium passes into another and bends at the intersection of the two materials.
Explanation
Refraction is the phenomenon that occurs when light passes from one medium to another and changes its direction. This bending of light happens at the intersection of the two materials. Refracting, on the other hand, is the present participle form of the verb "refract" and does not accurately describe the process of light bending at the interface of two materials. Therefore, the correct answer is refraction.Rate this question:

Refraction occurs because the _____________ in one material is different than the _______________ in the second. (Same word(s).)
Explanation
Refraction occurs because the speed of light in one material is different than the speed of light in the second. When light travels from one medium to another, it changes direction due to the change in speed. This phenomenon is known as refraction. The speed of light determines how fast it can travel through a material, and when it encounters a boundary between two materials with different speeds, it bends or changes direction.Rate this question:

The minimum angle for total internal reflection is called the ______________.
Explanation
The minimum angle for total internal reflection is called the critical angle. It is the angle of incidence at which the refracted ray lies along the boundary between two mediums, resulting in no transmission of light. This phenomenon occurs when light travels from a denser medium to a less dense medium. The critical angle determines whether light will be refracted or reflected, making it a crucial concept in optics and the study of light.Rate this question:

An added advantage of using light in for data transmission is that the fiber can carry multiple signals using different light ____________.
Explanation
An added advantage of using light for data transmission is that the fiber can carry multiple signals using different light frequencies. This means that different signals can be encoded on different frequencies of light, allowing for simultaneous transmission of multiple signals through the same fiber. By utilizing different frequencies, each signal can be separated and decoded at the receiving end, enabling efficient and high-capacity data transmission.Rate this question:
