A glass optical fiber is used to transport a light ray across a long distance
A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.540 and is submerged in glycerin, which has an index of refraction of 1.473. What is the critical angle (in degrees) for the light ray to remain inside the fiber?

(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...

Some biological systems can act like an optical fiber. Below is a drawing which illustrates how this might occur. Imagine you have a long, thin cell surrounded by fluid with index of refraction 1.38. The average index of refraction inside the cell is 1.48. Compute the critical angle, theta_crit, for total internal reflection for this system. Show all of your computations. What will the angle of refraction be for ray A (shown below) that has an angle of incidence of...
