When two mirrors are placed at an angle of 90º to each other, how many images will be formed when an object is placed in front of the mirrors
- 5
- 4
-
3
- 2
The correct answer is: C
Explanation
When two mirror are inclined at an angle θ, the number of images formed, n = \(\frac{360}{\theta}\) − 1
∴ since \(\theta\) = 90o
∴ \(\frac{360}{\theta}\) − 1
= 4 − 1
= 3
