A jar contains two immiscible liquids A and B with a coin at its bottom. The depths of liquid A and liquid B are 6 cm and 8 cm, respectively. If the apparent depth of the coin is 9 cm and refractive index of liquid A is 1.5, what is the refractive index of liquid B?

Explanation

To find the refractive index of liquid B, we can follow these steps:

### Step 1: Understand the problem
We have two immiscible liquids, A and B, with known depths and the refractive index of liquid A. We need to find the refractive index of liquid B.

### Step 2: Identify the given values
- Depth of liquid A (d_A) = 6 cm
- Depth of liquid B (d_B) = 8 cm
