- = The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs. Cheese file to unload Movimuvo filo cine: 20MDYA beam of light is traveling in air and strikes a material.
