Refraction



In the above figure, a ray of light is incident upon the interface between two media having indices of refraction n1 = 1.2 and n2 = ???. The known angles are f2 = 60° and f3 = 34°. (Note that the angles in the diagram may not be accurate.) What is the speed of light in the second medium?

v2 = m/s
