The speed of light v inside the optical fiber. b. The time it takes for that ray of light to travel the length from end to end if the ray travels in a straight line within the optical fiber.

A ray of sunlight traveling through water (n=1.32 - 1.34 across the visible spectrum) has an incident angle of 80° when it encounters a transparent aquarium wall with index of refraction n=1.2. There is air with index n=1 on the other side of the wall and the wall surfaces are parallel. Which statement below is true? Select one: a. Light emerges on the other side of the wall traveling parallel to the incident ray. b. Light emerges on the other side of the wall but different colors now travel in different directions. c. Light emerges on the other side of the wall and is now completely polarized. d. The light is completely reflected at the first interface. e. The light enters into the transparent wall bot is completely reflected at the second interface.
