Diamond has a high refractive index (2.42) and a low critical angle (24.4°). Light entering diamond undergoes multiple total internal reflections before exiting, creating a sparkling effect. Glass has a lower refractive index (~1.5) and higher critical angle, so less total internal reflection occurs. Section D: Lenses (Aktiviti 13.4) Question: A convex lens has a focal length of 10 cm.
