A coin placed at the bottom of a beaker appears to be raised by 4.0 cm. If the refractive index of water is 4/3, find the depth of the water in the beaker.

Explanation

To solve the problem, we need to find the depth of water in the beaker using the given information about the apparent rise of the coin and the refractive index of water.

### Step-by-Step Solution:

1. **Understanding the Refractive Index**:
The refractive index (μ) of a medium is defined as the ratio of the real depth (actual depth) to the apparent depth (depth perceived by an observer). The formula is given by:
\[
\mu = \frac{\text{Real Depth}}{\text{Apparent Depth}}
