and await the strictly practical directions which will be given later, on p.21. what followers can best be understood by considering the diagram, figure 2.2. here rays of light are considered passing from a dense medium into a rarer one, say from glass into air. the rays will then be refracted away from the normal, NOM (the revers process of the former case considered in figure 2.1).
