Using the equipment provided design a setup $($A handout is provided to get you started$)$ to determine the relationship that exists between the angle of incidence and the angle of reflection for light passing from air into a more optically dense medium $($cylindrical lens$)$ and vice versa. Record the data on worksheet. If the index of refraction fro Flat surface and curved surface were not the same, we would say that principle of reversibility would not hold in this case. That is if light traveled in opposite direction the law of refraction is should still hold. From your analysis would do you find?
