runs along the fiber's length. The core is surrounded by a medium with a lower index of refraction, typically a cladding of a different glass, or plastic. Light travelling in the core reflects from the core-cladding boundary due to total internal reflection, as long as the angle between the light and the boundary is less than the critical angle. As a result, the fiber transmits all rays that enter the fiber with a sufficiently small angle to the fiber's axis. The limiting angle is called the acceptance

Pamela Perez Abstract The purpose of this experiment was to observe and measure the reflection, refraction, and dispersion of light through mirrors, lenses, and prisms. The experiment involved the interactive use of light to measure quantities that could be used to find properties of the given materials. The results of our experiment yielded focal lengths of 56mm for a concave mirror and 76mm for a convex mirror as well as an index of refraction of acrylic plastic equal to 1.46, and 1.39 with a

Final examination Theory 1. Explain the dispersion of light by a transparent dielectric material. The phenomen of dispersion is connected to the fact that the refractive index is dependent on the wavelength. Due to dispersion, the light waves from a complex radiation are bent by different angles as they enter a dispersive medium and they may be visualized separately. The index of refraction of a transparent dielectric medium is defined as the ratio of the speed of an electromagnetic wave

converging lenses; nearsightedness can be corrected with diverging lenses ../ The total internal reflection is the complete reflection that takes place within a substance when the angle of incidence of light striking the surface boundary is greater than the critical angle ../ The critical angle is the angle of incidence at which the refracted light makes an angle of 90° with the normal ./ Total internal reflection occurs only when the light moves from a medium with higher index of reaction to one medium

Refraction, Reflection and Optics ITT Technical Institute Physical Networking – NT1310 11/10/2014 Refraction, Reflection and Optics Refraction The most common real life example used when discussing refraction is a straw in water. When a straw is placed in a glass of water and viewed from the side, it appears to be broken or bent. This is due to the difference in the refractive indices of air and water. Since water is denser than air, the straw appears to bend as the light it reflects is slowed

experiment is to study the laws of reflection, refraction, and total internal reflection; to measure the focal lengths of the mirrors with convex and concave surfaces; and to measure the index of refraction of water. Theory: If a ray of light is incident on a flat surface: the angle of incidence a is the angle that the incident ray makes with respect to the normal, which is a line drawn perpendicular to the surface at the point of incidence. The angle of reflection r is the angle that the reflected

the business entities should ensure that the relationships between its employees are cordial. Sour employee relations are tantamount to failure of businesses while cordial relations among employees are the key to success. In most incidents, senior employees do not have respect for the junior members of staff in certain organizations. This is encouraged by not providing a framework of what should be done to an employee who mistreats other employees because of his or her position. Each business should

Christina Louise C. Linaac 02/12/16 LS 127 - D Corporate Sustainability Reflection Paper The very insightful talk last Tuesday was about Corporate Sustainability and its impact on today’s rapidly changing world. Corporate Sustainability can be viewed as a new and evolving corporate management paradigm. It is an “approach that creates long-term shareholder value by embracing opportunities and managing risks that stem from economic, environmental, and social developments.” Being in the
