rface, Figure 83). The refracted ray is the ray after it strikes the refractingsurface {00 for the first surface, and OA for the secondsurface). INDEX OF REFRACTION 105 The angle of incidence is the angle between the incidentray and the perpendicular to the surface (angle i for thefirst surface,… … Figure 83. — Diagram Explaining Refraction of Light. The law of refraction: A ray of light passing from a raremedium into a denser medium always bends toward the per-pendicular, and a ray of light passing from a dense to a rarermedium always bends away from the perpendicular. 127.
