Question

the refractive index of glass with the respect to air is 3/2 and refractive index of water with respect to air is 4/3 what will be the refractive index of water with glass​

Answer 1

Answer:

this maths can be solved by finding speed of glass and speed of water separately taking speed in air be 3 × 10^8 m/s

answer is

$\frac{16}{9}$

Answer 2

Answer: 8/9

given,

Refractive index of water wrt air = 4/3

Refractive index of glass wrt air = 3/2

Refractive index of glass wrt water ( glass n water) = Ref. index of water/ Ref. index of glass

= 4/3 divided by 3/2

= 4/3 x 2/3

= 8/9
