- What documentation is required for the tests? The order of these steps is important, since it is the sequence of how one solves the problem of testing performance values for the component, subsystem or system and establishes the validity and precision of the measurement. Once one describes the test methodology itself, it is appropriate to describe the contributions to the uncertainty of the measurement potential errors and ways to reduce that uncertainty.
- Of course, after the test is completed, documentation is needed to validate the record of the tests. There is a lot of material to cover here, so let's get started Directions for taking this Fiber U self-study course: Prerequisites It is assumed that the student has a basic knowledge of fiber optics at least at the basic CFOT or CPCT level. Several case studies are included where students will be quizzed on their troubleshooting skills. You should complete all lessons including taking the quiz "Test Your Comprehension" at the end of every lesson. When you finish all lessons, go here to take the Fiber U Fiber Optic Testing Certificate of Completion Exam Please note: receiving this Fiber U Certificate of Completion does not include FOA certification or membership but it does become documentation of your knowledge of fiber optics and should be part of your portfolio of documented knowledge, other training and work experience that can qualify you to apply for FOA direct CFOT certification through the FOA "Work to Cert" program.
- More details on getting a Fiber U Certificate of Completion are on the last lesson. Read more about the Fiber U Certificate of Completion program. For information on the FOA "Work to Cert" direct certification program for those with industry experience, go here. Contact the FOA for more details and an application.
- ACTION The Art of Illusion Mirrors are used not only in carnival games or at amusement parks, but also to create optical illusions definition:something that deceives the eye by appearing other than it is. Different mirror types can be used to produce different types of illusions. For example, a never-ending illusion can be formed by using a series of plane mirrors. Artist Yayoi Kusama effectively used this technique to create her popular Infinity Mirrors art exhibit featured at the Art Gallery of Ontario in In this exhibit, it appears that the room goes on forever into the distance, the floor and ceiling filled with illuminated objects.
- Although the actual room is rather small, the plane mirrors continue to reflect back and forth, obeying the Law of Reflection, so we can never really tell where it ends. This optical illusion occurs because the object in front of the first mirror creates an image behind that mirror, which then becomes the object for the second mirror, generating a new image. With each reflection, these objects and images continue to seem farther away from the two mirrors. To learn more about how images in a plane mirror form by reflection, watch the following video. Plane Mirrors and Infinity Selfies You can actually create your own infinity mirror selfie! Here's how. When you place two plane mirrors parallel to each other and a certain distance apart, your reflection will be repeatedly reflected back and forth between both mirrors. You may have noticed this effect yourself in mirrored elevators or bathrooms. Plane mirrors always have the same image characteristics.
- The image size will always be the same as the original object size. This means that if you are looking at yourself in a plane mirror, your reflected face will appear to be the same size as your actual face. Using your knowledge of plane mirrors and how they can be used to give the impression of infinite reflections, create your own optical illusion with this infinity mirror selfie. To document your process and final product, you should: Use two mirrors to create your infinity mirror. Recall that the effect is created when a mirror is reflected back into another mirror.
- Include a picture of how you set up your mirrors to produce the infinity effect. Include a picture of yourself posing in front of the infinity mirror. If you are uncomfortable sharing a picture, inform your teacher and use a class-appropriate object to show the effect instead. Now, admire the beautiful artwork you have created! Share your photograph with your classmates and explain why your image looks the way it does. Outline the challenges you faced when setting up the picture in order to achieve the desired effect. You should also explain the process you followed in setting up your infinity mirror selfie.
- For example, where did you get your mirrors? How far apart did you have to place them for the best effect? Light Refraction Mirrors aren't the only things that produce distortion in what we see. You may have noticed the phenomenon of refraction definition:the phenomenon of light changing direction when it passes from one medium to another of different density while swimming or fishing, as it is frequently experienced in or around water.
- Watch the video entitled Making a Penny Disappear to see the power of refraction at work. To understand this phenomenon, we need to know that light rays travel in straight lines, which is why we draw them as arrows. Recall that sometimes light will not just reflect off substances, but will also pass through them fully if transparent or partially if translucent. Any substance through which light travels is called a medium definition:a substance that light passes through. The plural of medium is media. For example, glass, water and air are all types of media. When light is travelling through space or air, it encounters very little resistance, so travels at its top speed definition:about metres per second. That's about 7. This change in speed and direction of light is called refraction definition:the phenomenon of light changing direction when it passes from one medium to another of different density.
- The opposite is also true. Watch the short video below demonstrating how light interacts as it passes from air into different media. Rewatch the video as many times as you need so that you are able to answer the following questions. The phenomenon of light demonstrated in the video is important to understand and will be used in the rest of this activity.
- What Do You Think? The angle made by the refracted light ray with the normal is called the angle of refraction. How did this angle change when the light was refracted through different media? Glass is more optically dense than water and water is more optically dense than air. How can you use this information to explain or predict what the direction of the refracted light ray could be? How would you summarize what you saw in this video? The penny in the last video seemed to disappear because of the changing direction of light rays no longer pointing towards our eye. Think of some other times in your life when you have noticed a similar phenomenon. A pencil viewed through three media: air, glass and water. In the image above, do you notice how the sections of the pencil appear different from one another? This has to do with the speed and direction at which the light reflecting off the pencil is travelling. The light refracts when it reaches the glass and changes both, resulting in the pencil looking slightly larger through the glass alone.
- For a more detailed explanation, look at the answers to the questions below. Questions For these questions, refer to the image of the pencil in a glass of water. Why does the tip of the pencil appear the way it does? Light reflecting off the pencil travels from the pencil through air and towards our eyes at its regular speed. This results in no distortion of the pencil's appearance, so it appears normal. Answer Light reflecting off the middle of the pencil travels first through air at its regular speed, then through the glass at a lower speed changing its direction and then back into the air and towards our eyes again at its regular speed. Because the glass is thin, it results in a minor distortion of the pencil's appearance. Answer Light reflecting off the bottom of the pencil travels first through water at a much slower speed, then through the glass at a bit faster speed changing direction but still lower than normal, then finally back into the air changing its direction again and towards our eyes at its regular speed.
- This results in a major distortion of the pencil's appearance. Refraction and Reflection Refraction and reflection both deal with the change in direction of light. Look at the following diagrams which demonstrate how the change in direction is observed. Reflection Reflection deals with the change in direction of light as it bounces off a surface back into the same medium. The angle of reflection is equal to the angle of incidence.
- Refraction Refraction deals with the change in direction of light as it passes through a surface from one medium to another. The angle of refraction is not equal to the angle of incidence. Try This At Home! Did you know that you can use your knowledge of refraction to magnify things? For example, a water droplet placed on a newspaper is able to magnify the letters beneath it. Take a newspaper or magazine something you don't mind getting wet and cover it with some plastic wrap or a clear plastic bag. Use your pinky finger to place a drop of water gently on the letters. Due to refraction, the letters beneath the water should appear larger than the text surrounding it. What would happen if you were to make the drop of water larger?
- What would happen if you were to make the drop of water smaller? What would happen if you were to lift up the plastic to see how the distance from the letters changed the magnification? Check these out for yourself. Were your hypotheses correct?
