Choose all correct statements: Refractive index of medium A with respect to medium B is 4/3 and refractive index of medium A with respect to medium C is 3/2. 
 

Dear Student

All statements are correct.

Explanation:

Refractive index of medium A /  Refractive index of medium B =  4/3

Refractive index of medium A /  Refractive index of medium C = 3/2  

Dividing ,

Refractive index of medium C /  Refractive index of medium B

= 4/3 x 2/3

=8/9
So,  Refractive index of C with respect to B is 8/9

Refractive index of medium B  >   Refractive index of medium C

So, medium B is denser than C
Hence when light ray travels from B to C it bends away from normal

 speed of light in medium B /  the speed of light in medium A = refractive index of A / refractive index of B = 4 / 3
