Question

Refractive index of glass with respect to water is (9//8). Refractive index of glass with respect to air is (3//2). find the refractive index of water with respect to air .

Answer 1

Answer:

The refractive index of water to air is 0•75

Explanation:

The refractive index of air to water is 1•33

So to find the refractive index of water to air you find the reciprecle of 1•33,

It will be 1/1•33=0•75

Hope it's helpful!!!!

Answer 2

Given:

1. Refractive index of glass with respect to water is (9/8).
2. Refractive index of glass with respect to air is (3/2).

To find:

1. The refractive index of water with respect to air.

Answer:

• It is given that the refractive index of glass with respect to water is (9/8).
• Hence the refractive index of water with respect to glass is (8/9).
• It is also given that the refractive index of glass with respect to air is (3/2).
• Thus the refractive index of water with respect to air = refractive index of water with respect to glass × the refractive index of glass with respect to air = 8/9 × 3/2 = 4/3.

Thus the refractive index of water with respect to air is (4/3).
