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
Verified Correct Answer: C.
Physical Principles & Numerical Solution
When two mirror are inclined at an angle \theta, the number of images formed, n = \(\frac{360}{\theta}\) − 1
∴ since \(\theta\) = 90o
∴ \(\frac{360}{\theta}\) − 1
= 4 − 1
= 3
