Refractive index of medium B relative to A will be greater than unity.

Explanation:

  • As the light goes from medium A to B, the ray of light deviates towards normal.
  • So it has greater restrictive index and lesser velocity of light with respect to medium A.
  • Therefore, medium B must be denser compared to medium A.
  • The refractive index of medium B relative to A will be greater than unity.

Hence refractive index of medium B relative to A will be greater than unity.
