Refractive Index of B with respect to A
=(sin i)/(sin r)
=(sin 60)/(sin45)
=( √3 /2)/(1/ √2)
= √6/2
=1.225

Answer:√3/√2
Here angle of incidence is 60 degree.
And angle of refraction is 45 degree.
Explanation:
The Snell's law simply relates angles i and r to the refraction indices of the two media A and B. Therefore, refractive index of medium B relative to medium A is:
Sin i/ sin r = sin 60 / sin 45
√3/√2 multiplied by 2
(2 can be written as √2 ×√2)
√3 ×√2 divided by √2 ×√2
√2 /√2 will get cancelled
And the answer is
√3/√2
