As the angle between two mirrors decreases, the number of images formed increases. This is because a smaller angle results in more reflections within the mirror setup, leading to a higher number of images being visible.

Understanding Multiple Reflections in Mirrors
When two mirrors are placed at an angle to each other, they create multiple images of an object placed between them. The angle between the mirrors plays a crucial role in determining the number of images formed.
Number of Images Formula
The number of images (N) formed when two mirrors are inclined at an angle (θ) is given by the formula:
- N = (360/θ) - 1
This formula shows that the number of images depends on the angle between the mirrors.
Effect of Decreasing the Angle
As the angle θ decreases:
- The value of (360/θ) increases because the denominator is getting smaller.
- Consequently, N (the number of images) increases.
Infinite Images at Zero Angle
When the angle approaches zero:
- The mirrors become parallel.
- In this case, an infinite number of reflections occur, creating an infinite series of images.
Conclusion
Thus, as the angle between the two mirrors decreases, the number of images formed increases, and can potentially become infinite if the mirrors are parallel. This phenomenon illustrates the fascinating behavior of light and reflections in optics.
In summary, the correct answer is option 'C': The number of images increases as the angle between two mirrors decreases.

Read the given passage and answer the questions:Metallic Character: The ability of an atom to donate electrons and form positive ions (cation) is known as electro-positivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size. Non-Metallic Character: The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion. Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electro -negativity increases due to decrease in atomic size.Identify the reason for the gradual change in electronegativity in halogens down the group.
