A ray of light enters parallel to the axis of a hollow cylindrical tube. When the tube has only air, the light takes 18.6 ns to travel the full length of the cylinder, but when the tube is filled with a transparent substance, it takes 7.1 ns longer to travel by comparison. What is the refractive incidence of that substance?

A ray of light strikes a flat glass block at an incidence angle of ?1 = 34.4°. The glass is 2.00 cm thick and has an index of refraction that equals ng = 1.20. A light ray incident on a glass block of thickness 2.00 cm is shown. The ray travels down and to the right and is incident to the top of the block at an angle ?1 to the normal of the surface. The ray inside the block moves down and to the right but at a steeper slope than the incident ray, making an angle of ?2 with the vertical. It is incident on the bottom surface of the block, making an angle of ?3 with the vertical, and exits moving down and to the right, at a less steep slope, making an angle of ?4 with the vertical.
