When an object is placed between two parallel mirrors, then number of images formed are

Options

A. 2
B. 4
C. 8
D. Infinite

Answer

To determine the number of images formed when an object is placed between two parallel mirrors, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have two parallel plane mirrors facing each other.
- An object is placed between these two mirrors.

2. **Formation of Images**:
- When light from the object hits the first mirror, it reflects and forms an image.
- This image acts as a new object for the second mirror, which reflects it to form a second image.
- The process continues, with each image acting as an object for the opposite mirror.

3. **Infinite Reflections**:
- Since the mirrors are parallel, the reflections will continue indefinitely.
- Each image formed will create another image in the opposite mirror, leading to an infinite series of images.

4. **Conclusion**:
- Therefore, the total number of images formed by two parallel mirrors when an object is placed between them is infinite.

### Final Answer:
The number of images formed is **infinite**.
