Problem 1: Light travels from air into an optical fiber with an index of refraction of 1.44. (a) In which direction does the light bend? (b) If the angle of incidence on the end of the fiber is 22 degrees, what is the angle of refraction inside the fiber? (c) Sketch the path of light as it changes media. Problem 2: ? Light traveling through an optical fiber (n=1.44) reaches the end of the fiber and exits into air. (a) If the angle of incidence on the end of the fiber is 30 degrees, what is the angle of refraction outside the fiber? (b) How would your answer be different if the angle of incidence were 50 degrees
