A laser beam is pointed so that it passes through side A of the triangular glass (n = 1.5) prism shown below at an angle of incidence of 0o. The ray then strikes the far side of the prism (the hypotenuse). This experiment is conducted first when the prism is surrounded by air (n = 1) and then when the prism is surrounded by water (n = 1.33). Determine whether the light from the laser will pass through the hypotenuse of the prism when (a) the prism is in air and (b) the prism is in water. If it will, determine the angle of refraction in each medium

The figure shows an optical fiber in which a central plastic core of index of refraction n1 = 1.60 is surrounded by a plastic sheath of index of refraction n2 = 1.52. Light can travel along different paths within the central core, leading to different travel times through the fiber. This causes an initially short pulse of light to spread as it travels along the fiber, resulting in information loss. Consider light that travels directly along the central axis of the fiber and light that is repeatedly reflected at the critical angle along the core-sheath interface, reflecting from side to side as it travels down the central core. If the fiber length is 370 m, what is the difference in the travel times along these two routes? NUmber i 99 Units ns

A ray of monochromatic light is reflected and refracted, as shown in the figure, in the point “A” at the interface between material 1 with refractive index n1 = 1.54 (chloride of sodium) and material 2 with refractive index n2 = 1.77 (sapphire). The incident lightning forms an angle of 55 ° to the interface. The light that penetrates material 2, at point “A”, arrives then to point “B” at the interface between material 2 and material 3, which is air (n3 = 1), the interface through "B" being parallel to the interface through "A". In "B" part of the light is reflected and the rest enters the air. What is the angle of refraction in air? a) 62.04 ° b) 55 ° c) 29.93 ° d) 35 °

A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.520 and is submerged in ethyl alcohol, which has an index of refraction of 1.361. What is the critical angle (in degrees) for the light ray to remain inside the fiber?

An engineer is carrying out an experiment to determine the index of refraction for a partially reflective material. To do this, she aims a narrow beam of light at a sample of this material, which has a smooth surface. She then varies the angle of incidence. (The incident beam is traveling through air.) The light that gets reflected by the sample is completely polarized when the angle of incidence is 59.5°.
