2. Did the light bend toward or away from the side of the container as it left the water?
3. Were the angles measured in steps 10 and 11 equal?
4. How did the direction of the light ray entering the water compare to the direction of light leaving the water?
5. A light ray enters a piece of glass from air at an angle of 35 degrees. Use the diagram below to answer the questions.
a. At what angle did the light ray leave the glass?
b. Draw the line inside the glass representing the path of light inside the glass.
c. Are the angles between the light rays and the surface of the glass smaller inside or outside the glass?
d. When the angles between the light rays and the surface of the glass become larger, does that represent light speeding up or slowing down?
