1)

Why are fibers birefringent

-because the fiber is a natural fiber

-because the fiber has long range orientation (order)

-because the fiber has a refractive index greater than 1.52

-because the refractive index is less than 1.52

2)

- burn testing

-solvent testing

-refractive index

-tensile testing

Answer #1

1. The fibers are birefringent because the fiber has long range orientation (order).

2. Tensile test individualizes the fibre evidance. The equipment used for this test is called as fibre proof tester and which measures the tensile strength of fibre.

    (2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...

    Polymer composite materials have gained popularity because they have high strength to weight ratios and are relatively easy and inexpensive to manufacture. However, their nondegradable nature has prompted development of environmentally friendly composites using natural materials. An article reported that for a sample of 10 specimens with 2% fiber content, the sample mean tensile strength (MPa) was 51.1 and the sample standard deviation was 1.2. Suppose the true average strength for 0% fibers (pure cellulose) is known to be 48...

    1. When Abrams and Townsend investigated the natural selection of copepods that avoid predation of bioluminescent dinoflagellates, which of the following best states the hypothesis they were testing? A. The bioluminescent dinoflagellates produce enough light that they can also photosynthesize at night, harming the copepods. B. The light emitted by bioluminescent dinoflagellates is of sufficient wavelength and energy to be dangerous to feeding copepods. C. Bioluminescent flagellates benefit from selection of flashing, because it startles the copepods. D. Copepods that...

    Problem 1: Fibre optics (2 points) Figure 1: Sketches of the geometry of an optical fibre A long cylinder of dielectric material can guide light via total internal reflection. This idea dates back to the 1870s and forms the basis of the modern fibre optics communication technology. As long as the diameter of these fibres is large compared to the wavelength of the infalling light, its wave nature is negligible and we can use Geometric Optics to study the propagation...

    Two professors at a local college developed a new teaching curriculum designed to increase students' grades in math classes. In a typical developmental math course, 48% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 17 students enrolled, 11 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the a=0.1 level of significance? Complete parts (a) through (g). Because...
