When two plane mirrors are placed so that the angle between them is 60°, how many images of an object are produced?

1. 5
2. 6
3. 7
4. 8

Correct answer: 5

Solution

When two mirrors are positioned at an angle of 60°, the number of images formed can be calculated using the formula (360°/angle) - 1. In this case, (360°/60°) - 1 equals 6 - 1, resulting in 5 images.
