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 \(\theta\)
- 30o
-
45o
- 51o
- 90o
The correct answer is: B
Explanation
Number of image = \(\frac{360}{\theta}\) -17 = \(\frac{360}{\theta}\) -1
thus,\(\theta\) = 45o
