An object is placed 1.5m from a plane mirror. How far is the image from the object?

Options

A. 3m
B. 1.5m
C. 2m
D. 1m

Explanation

To solve the problem of how far the image is from the object when the object is placed 1.5 meters from a plane mirror, follow these steps:

### Step-by-Step Solution:

1. **Identify the Distance of the Object from the Mirror**:
- The object is placed 1.5 meters away from the plane mirror.

2. **Understand the Properties of Plane Mirrors**:
- A plane mirror creates an image that is the same distance behind the mirror as the object is in front of it. This means that if the object is 1.5 meters in front of the mirror, the image will also be 1.5 meters behind the mirror.

3. **Calculate the Distance of the Image from the Mirror**:
- Since the object is 1.5 meters from the mirror, the image will also be 1.5 meters from the mirror on the opposite side.

4. **Determine 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 from the object to the mirror = 1.5 meters
- Distance from the mirror to the image = 1.5 meters
- Therefore, the total distance between the object and the image = 1.5 meters + 1.5 meters = 3 meters.

5. **Conclusion**:
- The image is 3 meters away from the object.

### Final Answer:
The image is 3 meters away from the object.
