A fish in water sees an object which is `24cm` above the surface of water. The height of the object above the surface of water that will appear to the flash is `(mu=4//3)`

Options

A. `24cm`
B. `32cm`
C. `18cm`
D. `48cm`

Explanation

To solve the problem of finding the apparent height of an object above the surface of water as seen by a fish, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Given Information**:
- The actual height of the object above the surface of the water (h) = 24 cm.
- The refractive index of water (μ) = 4/3.

2. **Use the Formula for Apparent Height**:
- The formula to find the apparent height (h') as seen by an observer in a different medium is given by:
\[ h' = h \times \mu \]
- Here, h is the actual height and μ is the refractive index.

3. **Substitute the Values into the Formula**:
- Substitute h = 24 cm and μ = 4/3 into the formula:
\[ h' = 24 \, \text{cm} \times \frac{4}{3} \]

4. **Calculate the Apparent Height**:
- Perform the multiplication:
\[ h' = 24 \times \frac{4}{3} = \frac{96}{3} = 32 \, \text{cm} \]

5. **Conclusion**:
- The height of the object that will appear to the fish is 32 cm.

### Final Answer:
The apparent height of the object above the surface of water as seen by the fish is **32 cm**.
