An object is placed in front of two plane mirrors inclined at an angle of 0o. If the total number of images formed is 7, Find the value of \(\theta\)
A
30o
B
45o
C
51o
D
90o
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Number of image = \(\frac{360}{\theta}\) -1
7 = \(\frac{360}{\theta}\) -1
thus,\(\theta\) = 45o
