Question

The refractive indicaes of glass and water are 3÷2 and 4÷3 respectively. The refractive index of glass with respect to water is:​

Answer 1

Answer:

please mark me as brainliest

Explanation:

R. I. of glass =  3 /2

R. I. of water =  4/3

R. I. of glass with respect to water  

=  

R.I.of glass/

R.I.of water

=  3/2 /4/3

​=8 /9
