To find the number of images formed when an object is placed between two mirrors, we use the formula:

N = (360°/θ) - 1

Where:
- N represents the number of images formed
- θ represents the angle between the mirrors



When an object is placed between two mirrors, multiple images are formed due to the repeated reflection of light. The number of images formed depends on the angle between the mirrors.

When the angle between the mirrors is such that the reflected rays from both mirrors meet, we get one image. This is the primary image.

As we increase the angle between the mirrors, additional images are formed. Each additional image is formed by considering the path of light rays as they reflect between the mirrors.


- The angle between the mirrors is denoted by θ.
- The total angle of a circle is 360°.
- Each image is formed when the reflected rays from both mirrors meet.
- The formula (360°/θ) - 1 calculates the number of images formed.



Let's consider an example where the angle between the mirrors is 60°.

Using the formula:

N = (360°/θ) - 1
N = (360°/60°) - 1
N = 6 - 1
N = 5

Therefore, in this case, 5 images will be formed when an object is placed between two mirrors with an angle of 60°.



Formula for finding the number of images formed in multiple images using two mirrors:
- N = (360°/θ) - 1

Explanation:
- When an object is placed between two mirrors, multiple images are formed due to the repeated reflection of light.
- The number of images formed depends on the angle between the mirrors.
- Each image is formed when the reflected rays from both mirrors meet.

Key Points:
- The angle between the mirrors is denoted by θ.
- The total angle of a circle is 360°.
- Each additional image is formed by considering the path of light rays as they reflect between the mirrors.

Example:
- Angle between mirrors (θ) = 60°
- N = (360°/60°) - 1
- N = 6 - 1
- N = 5

Therefore, when an object is placed between two mirrors with an angle of 60°, 5 images will be formed.
