Question

What will be θ / angle between two mirrors if the number of images formed is 12??

Answer 1

30

Explanation:

no. of images n=360/theeta

12=360/theeta

theeta=360/12

theeta=30.

Answer 2

Answer:

If two mirrors inclined at some angle then there be formation of images more than one are called Multiple Reflection.

It's formula is written in the form of:

No. Of images=360°/Angle-1

No. Of images=12

12=360°/Angle-1

12+1=360°/Angle

13=360°/Angle

Angle=360°/13

Angle=27.6923 Ans.
