Problem 4 At the interface between two different clear substances a beam of light crossing from one to the other has an angle of incidence (6.) of 20 degrees and an angle of refraction (C:) of 30 degrees. ni n2 1.) Draw the incident ray and the refracted ray, approximating the correct angles. Label 8, and e. 2.) If n = 2.05, what is the value of n,? 3.) Is the speed of light faster in medium n, or ne? Bonus: At what (smallest) angle of incidence would the incident ray reflect from the surface instead of crossing into medium 2?
