Question

- You are given three medium XYZThe refractive, index of the three medium n1 n2 n3
a ln which of these does the light travel fastest?
b in which of these does the light travel lowest?
C.arrange the medium in assending order of their optical density​

Answer 1

Given:

You are given three medium XYZThe refractive, index of the three medium n1 n2 n3

To find:

a ln which of these does the light travel fastest?

b in which of these does the light travel lowest?

C.arrange the medium in ascending order of their optical density​

Solution:

Let us consider,

n1 = 1, n2 = 2, n3 = 3

So, we have,

a ln n3 = 3 the light travel fastest

b in n1 = 1 the light travel lowest

C. The arrangement of  the medium in ascending order of their optical density​ is as follows:

n3 < n2 < n1

Answer 2

Answer:

The question is not complete and the above answer given by qwyellow is therefore wrong anyway I will give the correct question and correct answer for it.

I have verified it from book

Explanation:

The attached image is the correct question, the question does not contain the highlighted part

Answer:

When refractive index is high, the speed of light is less and if the refractive index is less then speed of light is high

Answer of (a) :n2

Answer of (b) :n1

Answer of (c) :ascending order

n2, n3, n1
