Statement I: A beam of white light enters the curved surface of a semicircular piece of glass along the normal. The imcoming beam is moved clockwise (so that the angle `theta` increases), such that the beam always enters along th enormal to the curved side. Just before the refracted beam disappears, it becomes predominantly red.
Statement II: The index of refraction for light at the red end of the visible spectrum is more than at the violet end.
