Question
They x-y plane is the boundary between two transparent media. Medium-1 with z > 0 has refractive index √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√3ˆi+8√3ˆj−10ˆk is incident on the plane of separation. If the unit vector in the direction of refracted ray in medium-2 is 10√x3. Then x is :
