What is the critical angle for total internal reflection so that the beam stays within the fiber? b. What would the critical angle be if the fiber were completely immersed in water (n = 1.33)?

A physicist directs a laser beam through a transparent medium, toward one surface of an equilateral prism. (The beam travels, and remains in, the plane of the page.) Incident on Surface 1 at an angle ?1, the beam then encounters Surface 2 from within the prism.
If the angle of incidence at Surface 2 equals ?c , the critical angle for this prism, what is the original incidence angle, ?1 (in degrees)? The critical angle in this case is ?c = 40.5°.

A prism in the shape of an equilateral triangle is shown. The triangle is upside down such that the base of the triangle is at the top of the figure and the apex is at the bottom. A laser beam comes in from the top left, moves down and to the right and is incident on the center of the base of the triangle. This surface is labeled Surface 1. The incident beam makes an angle of ?1 with the vertical. Within the prism, the beam continues to move down and to the right but at a slope which is steeper than the initial beam. It is incident…

Part (a) What angle of incidence (θ1θ1) does the ray from the person’s face make with the perpendicular to the water at the point where the ray enters? The angle of refraction (θ2θ2) between the ray in the water and the perpendicular to the water is 37.1°.

- A light ray is incident on an interface between water (n = 1.333) and air (n = 1.0002926) from within the air. If the angle of incidence in the air is 30.0, what is the angle of the refracted ray in the water?arrow_forwardAn optical fiber with circular cross section has refractive index 1.45. It’s surrounded by a cladding with refractive index 1.43. (a) Find the maximum angle relative to the fiber axis at which light can propagate down the fiber by undergoing successive to-tal internal reflections. (b) Find the speed of light in the fiber. (c) For the angle you found in part (a), find the speed at which light actually makes its way along the fiber—that is, the length of fiber that the light traverses per unit time. Note that this isn’t the same as your answer to (b) because the light bounces back and forth rather than following a straight path along the fiber.arrow_forwardLight traveling through an optical fiber (n=1.44) reaches the end of the fiber and exits into air.
