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 44.7 ?44.7? ? 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 =
