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
-
A.
5 -
B.
4 -
C.
3 -
D.
2
Correct Answer: Option 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
