Question

viii) The refractive index of the water is 4/3, Glass is 3/2 and oil is 5/4. The order of speed of light in

these medium is

a) Oil > Glass > Water b) Water > Glass > Oil c) Glass > oil > water d) Oil > Water > Glass​

Answer 1

Answer:

Refractive indices:

1. Water = 1.33

2. Glass = 1.5

3. Oil = 1.51

[The values didn't make sense. Water has the highest speed of light.]

Hence, (b) - Water>Glass>Oil
