The refractive of three media are given below :
`{:("Medium",A,B,C),("Refractive index",1.65,1.71,1.47):}`
A light ray travels from medium A to medium B and another light ray travels from medium B to medium C. In which case does (a) the refracted ray bend towards the normal (b) the speed of light will be more.

Explanation

(a) The refracted ray bend towards the normal when the light ray travels from medium A(rarer) to medium B (denser).
(b) Speed of light is more in a optically rarer medium i.e., a medium with the lowest value of refractive index. In this case it is medium C.
