What is the number of images of an object formed by two mirrors if the angle between the mirrors is in between 2π/4 and 2π/5 ?
Answer & explanation
Correct answer: option 4
As we know, if angle between two mirrors is between $\frac{2π}{n}$ and $\frac{2π}{n+1}$ then the no. of images formed is ‘n’
So here in the question it is $\frac{2π}{4}$ and $\frac{2π}{4+1}$
∴ no. of images will be 4.
