An object is at a distance of `1.2m` in front of a plane mirrorr. Distance between the object and image is

Options

A. `0.5 m`
B. 1 m
C. `0.25 m`
D. `1.5 m`

Explanation

To solve the problem of finding the distance between an object and its image in front of a plane mirror, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Distance of the Object from the Mirror**:
- The object is placed at a distance of 1.2 meters in front of the plane mirror.

2. **Determine the Position of the Image**:
- In the case of a plane mirror, the image is formed at the same distance behind the mirror as the object is in front of it. Therefore, the image will also be 1.2 meters behind the mirror.

3. **Calculate the Total Distance Between the Object and the Image**:
- The total distance between the object and the image can be calculated by adding the distance from the object to the mirror and the distance from the mirror to the image.
- Distance between object and image = Distance from object to mirror + Distance from mirror to image
- This can be expressed as:
\[ \text{Distance} = 1.2 \, \text{m} + 1.2 \, \text{m} = 2.4 \, \text{m} \]

4. **Conclusion**:
- The distance between the object and its image is 2.4 meters.

### Final Answer:
The distance between the object and the image is **2.4 meters**.
