    A light ray hits a surface at an angle of 5o. The material on the other side of the surface has an index of refraction of 1.87 and the light is making an angle of 4.062o with the surface when it exits on this side. What is the index of refraction on the incident side of the interface?

    ?

    A light ray hits a surface at an angle of 33o. The material on the other side of the surface has an index of refraction of 1.13 and the light is making an angle of 75.64o with the surface when it exits on this side. What is the index of refraction on the incident side of the interface?

    ?

    A light ray hits a surface at an angle of 46o. The material on the other side of the surface has an index of refraction of 1.66 and the light is making an angle of 70.85o with the surface when it exits on this side. What is the index of refraction on the incident side of the interface?
