(Questions 4,5) A monochromatic beam of yellow light, AB, is incident
upon a Lucite block in air at an angle of 33°. Find the angle of refraction. Draw the refracted ray
Base your answers to questions 6 and 7 on the information and diagram
below. In the diagram, a light ray, R, strikes the boundary of air and
water.
6. Using a protractor, determine the angle of incidence. (hint:
Draw the normal first)
7. Using a protractor and straightedge, find and draw the refracted ray on the
diagram b
