Question

Stephen is given a large crystal and needs to verify whether it is a diamond or cubic zirconia. He shines a beam of light at a 42.2 angle upon the face of the crystal and measures the refraction angle. What is the refraction angle if the crystal is a diamond? refraction angle for diamond What is the refraction angle if the crystal is a cubic zirconia? refraction angle for cubic zirconia

Answer 1

5 3 Ansurer c idence angle lů = 42.2° Reformative index of air (u) = 1 1.) Repsactive index of diamond (42)= 214 • APPLY Shell's Low Sink) = 4, since) sin (8)= lx sin (42.2) 2.4 resint 10:27) r = 15.56 lid Refractive index of zirconia (4₂) = 2.15 sin (8) = 4, sinli) = 1x sin (42.2) 2183 r = sin 10.312) go 1817°
