Question

If you stand in a rectangular room, where two adjacent walls are covered with plane mirrors, the total number of your images will be
1. infinity
2. 1
3. 3
4. 0

Answer 1

Correct Answer - Option 3 : 3

The correct answer is 3.

• The number of images (n) formed by two mirrors inclined to each other at an angle x is given by (360/x) - 1.
• Here, all the mirrored walls are perpendicular, that is x = 90 degrees.
• Considering two adjacent walls, so the number of Images formed will be (360/90) - 1= 4 - 1 = 3
