Two mirrors are placed at right angle to each other. A man is standing between them combining his hair. How many images he will see?

Options

A. 2
B. 3
C. 1
D. zero

Explanation

To determine how many images a man will see when standing between two mirrors placed at right angles (90 degrees) to each other, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Configuration**:
- We have two mirrors placed at an angle of 90 degrees to each other.

2. **Use the Formula for Number of Images**:
- The number of images (m) formed by two mirrors can be calculated using the formula:
\[ m = \frac{360^\circ}{\theta} - 1 \]
- Here, \(\theta\) is the angle between the two mirrors.

3. **Substitute the Angle**:
- In this case, since the mirrors are at right angles, we have:
\[ \theta = 90^\circ \]

4. **Calculate the Number of Images**:
- Substitute \(\theta\) into the formula:
\[ m = \frac{360^\circ}{90^\circ} - 1 \]
- Simplifying this gives:
\[ m = 4 - 1 = 3 \]

5. **Conclusion**:
- Therefore, the man will see a total of 3 images of himself in the mirrors.

### Final Answer:
The man will see **3 images**.
