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. (a)2
B. (b)3
C. (c)1
D. (d)zero

Answer

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 Setup**:
- We have two mirrors positioned at a right angle (90 degrees) to each other.
- The man is standing between these mirrors.

2. **Identify the Angle Between the Mirrors**:
- The angle (θ) between the two mirrors is given as 90 degrees.

3. **Use the Formula for Number of Images**:
- The formula to calculate the number of images (n) formed by two mirrors at an angle θ is:
\[ n = \frac{360}{\theta} - 1 \]
- Here, θ is the angle between the two mirrors.

4. **Substitute the Value of θ**:
- Plugging in the value of θ:
\[ n = \frac{360}{90} - 1 \]

5. **Calculate the Value**:
- Calculate \( \frac{360}{90} \):
\[ n = 4 - 1 \]
- Therefore, \( n = 3 \).

6. **Conclusion**:
- The man will see **3 images** of himself when standing between the two mirrors.

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