#### Solution

If an object is placed midway between two parallel plane mirrors facing each other, then the number of images that will appear in mirrors is **Infinite**

**Explanation:**

If two plane mirrors are placed together on one of their edges so as to form a right angle mirror system and then the angle between them is decreased, some interesting observations can be made. In fact as the angle between the mirrors approaches 0 degrees (i.e., the mirrors are parallel to each other), the number of images approaches infinity.
