3. Place the triangular prism on the whiteboard with the triangular edge facing down, as shown in the top view diagram below. Shine the red (in-person) laser at one edge of the prism such that it has a large angle of incidence, as shown. For the remote section: Make sure that the "reflections” box is checked. a) How many rays of light leave the prism? Make a sketch on the diagram and record any additional observations. b) For each of the rays that leave the prism, state how many reflections and refractions occurred. Indicate these on the diagram and sketch the path that light travels. c) Describe what happens if you decrease the angle of incidence, as shown at right. Record your observations using both diagrams and words.
