Let xxx-zzz plane be the boundary between two transparent media. Medium 111 in z≥0z \ge 0z≥0 has a refractive index of 2\sqrt 22​ and medium 222 with z<0z \lt 0z<0 has a refractive index of 3.\sqrt 3 .3​. A ray of light in medium 111 given by the vector A→=63i^+83j^−10k^\overrightarrow A = 6\sqrt 3 \widehat i + 8\sqrt 3 \widehat j - 10\widehat kA=63​i+83​j​−10k is incident on the plane of separation. The angle of refraction in medium 222 is:
