D. 6

Answer

To solve the problem of finding the number of real images formed by two plane mirrors inclined at an angle of \(60^\circ\), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have two plane mirrors inclined at an angle of \(60^\circ\).
- A light bulb (the object) is placed between these two mirrors.

2. **Using the Formula for Number of Images**:
- The formula to calculate the number of images formed by two mirrors inclined at an angle \(\theta\) is given by:
\[ N = \frac{360^\circ}{\theta} - 1 \]
- Here, \(N\) is the number of images and \(\theta\) is the angle between the mirrors.

3. **Substituting the Angle**:
- In this case, \(\theta = 60^\circ\).
- Plugging this value into the formula:
\[ N = \frac{360^\circ}{60^\circ} - 1 \]

4. **Calculating the Number of Images**:
- First, calculate \(\frac{360^\circ}{60^\circ}\):
\[ \frac{360}{60} = 6 \]
- Now, substituting back into the formula:
\[ N = 6 - 1 = 5 \]

5. **Conclusion**:
- Therefore, the number of real images formed by the two mirrors is \(5\).

### Summary:
The number of real images formed by a light bulb placed between two mirrors inclined at an angle of \(60^\circ\) is \(5\).
