Question

speed of light in medium A and medium B are 25 x 10^8 m/s and 2 x 10^8 m/s respectively then the refractive index of medium A with medium B will be?​

Answer 1

Answer:

2/25

Explanation:

AS WE KNOW,

RI=c/v

;; RI of a =c/v of a

;; RI of b =c/v of b

RI of a with respect to b= RI of a/ RI of b

                                       = (c/v of a)/ (c/v of b)

                                       = v of b/ v of a

                                        =2*10^8/25*10^8

RI of a with respect to b =2/25

RI of a / RI of b=2/25                  ANS......
