2. [-/20 points) DETAILS SERCP7 22.P.026. MY NOTES Three sheets of plastic have unknown indices of refraction. Sheet 1 is placed on top of sheet 2, and a laser beam is directed onto the sheets from above so that it strikes the interface at an angle of 26.8° with the normal. The refracted beam in sheet 2 makes an angle of 32.40 with the normal. The experiment is repeated with sheet 3 on top of sheet 2, and with the same angle of incidence, the refracted beam makes an angle of 36.2° with the normal. If the experiment is repeated again with sheet 1 on top of sheet 3, what is the expected angle of refraction in sheet 37 Assume the same angle of incidence. 3.
