Let the XZ plane be the boundary between two transparent media. Medium 1 in Z ge 0 has a refractive index of sqrt2 and medium 2 with Z gt 0 has a refractive index of sqrt3. A ray of light in medium 1 given by the vector ,vec(A) = 6sqrt3hat(i) + 8 sqrt3hat(j) - 10hat(k) is incident on the plane of separation. The light of refraction in medium 2 is
