Question

If we want 9 images of an object what arrangements of two mirrors and object should be done. ​

Answer 1

Answer:

answer : 36°

explanation : The number of images formed between two plane mirrors inclined at an angle θ to each other is given by formula, n = (360/θ) - 1.

case 1 : when (360/θ) is an even integer then number of image formed , n = (360/θ) - 1

case 2 : if (360/θ) is an odd integer and object is kept symmetrically

then number of image formed , n = (360/θ) -1

and if object is kept asymmterically then number of image formed, n = (360/θ).

Let's assume that object is kept as symmetrically.

then , number of image formed , n = (360/θ) - 1

⇒9 = (360/θ) - 1

⇒ 9 + 1 = 360/θ

⇒θ = 36°
