What happens to the beam of light that is incident on the interface between two different media - for example, ray 1 reaching the top surface of the water or ray 3 reaching the bottom? Q1.2: Label each ray as Incident, Reflected, or Refracted. Q1.3: How do you label ray 3? Discuss why it can have two labels. Q1.4: For the three situations illustrated, describe any pattern(s) you observe when looking at rays 1 and 2 or rays 3 and 4. Q1.5: For the three situations illustrated, describe any pattern(s) you observe when looking at rays 1 and 3 or rays 3 and 5. Q1.6: Part a, of the figure below, depicts the path of light rays moving from air into water and then out again. Note the bending of the light at the interfaces between the two media. In particular, keep track of the path of light relative to the normal (dashed) lines that are perpendicular to the interfaces. Based on the patterns you ob
