Options

A. 2
B. 3
C. 4
D. Infinity

Answer

To solve the problem of determining the number of images formed by two parallel plane mirrors, we can follow these steps:

### Step 1: Understand the Setup
We have two plane mirrors that are parallel to each other. Let's denote them as Mirror 1 and Mirror 2. An object is placed between these two mirrors.

**Hint:** Visualize the setup by drawing two parallel lines (representing the mirrors) and placing an object between them.

### Step 2: Determine Image Formation
When light rays from the object hit the first mirror, they reflect and create an image. This image acts as a virtual object for the second mirror, which will also create an image. This process continues back and forth between the two mirrors.

**Hint:** Remember that each image formed acts as a new object for the other mirror.

### Step 3: Count the Images
In the case of two parallel mirrors, the number of images formed is theoretically infinite. This is because each image formed by one mirror will create another image in the opposite mirror, leading to an endless cycle of image formation.

**Hint:** Think about how each image reflects back and forth between the two mirrors without any loss.

### Step 4: Conclusion
Thus, when two plane mirrors are parallel to each other, the number of images of an object placed between them is infinite.

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