Image formed by a plane mirror is

Options

A. virtual, behind the mirror and enlarged.
B. virtual, behind the mirror and of the same size as the object
C. real at the surface of the mirror and enlarged.
D. real, behind the mirror and of the same size as the object.

Explanation

To answer the question "Image formed by a plane mirror is," we need to analyze the characteristics of the image produced by a plane mirror. Here’s a step-by-step breakdown:

### Step 1: Understand the Nature of the Image
A plane mirror produces an image that is not real. Instead, it creates a virtual image. A virtual image is one that cannot be projected onto a screen because the light rays do not actually converge at the image location.

**Hint:** Think about whether the image can be captured on a screen or not.

### Step 2: Location of the Image
The virtual image formed by a plane mirror appears to be located behind the mirror. This is because the light rays reflecting off the object seem to originate from a point behind the mirror when extended backward.

**Hint:** Visualize the reflection and where the light rays appear to come from.

### Step 3: Size of the Image
The size of the image formed by a plane mirror is equal to the size of the object. This means that if you have an object of a certain height, the image will have the same height.

**Hint:** Consider how the dimensions of the object relate to the dimensions of the image.

### Step 4: Distance from the Mirror
The distance of the image from the mirror is the same as the distance of the object from the mirror. If the object is placed 3 meters in front of the mirror, the image will appear to be 3 meters behind the mirror.

**Hint:** Think about the symmetry of the setup with respect to the mirror.

### Conclusion
Based on the above points, we can summarize that the image formed by a plane mirror is:
1. Virtual
2. Located behind the mirror
3. Of the same size as the object
4. The distance from the mirror to the image is equal to the distance from the mirror to the object

Thus, the correct answer to the question is:
**Option 2: Virtual behind the mirror and of the same size as the object.**
