If two mirrors are kept inclined at 60° to each other and a body is placed at the middle, then total number of images formed is

1. six
2. five
3. four
4. three

Correct answer: five

Solution

The formula for the number of images formed by two inclined mirrors is given by n = (360°/θ) - 1, where θ is the angle between the mirrors. Substituting θ = 60°, we get n = (360°/60°) - 1 = 6 - 1 = 5. Hence, five images are formed.
