Question

Case 2: Water-Air. Change the top medium to water and the bottom medium to air. Fill in the table below.

Water ?Air Index of Refraction (Water) 1.33
Index of Refraction (Air) 1.0003

Angle of Incidence (degrees) Angle of Reflection (degrees) Angle of Refraction (degrees)
10 10.0 13.3
30 30.0 41.7
45 45.0 70.1
60 60.0 ----
80 80.0 ----



State the direction in which the refracted ray bends (toward the normal or away from the normal). You can determine this from the diagram or from the comparison of refracted angle to reflected angle.
