Question
The x-y plane is the boundary between two transparent media. Medium-1 with z > 0 has index refractive √2 and medium - 2 with z < 0 has a refractive index √3. A ray of light in medium - 1 given by the vector A=6√3^i+8√3^j−10^k is incident on the plane of separation.Find the unit vector in the direction of refracted ray in medium -2.
