What Is an Angle Between Mirrors Apparatus?
The Angle Between Mirrors Apparatus is designed to demonstrate the formation of images using two plane mirrors positioned at a selected angle. When light from an object reflects between the mirrors, more than one image may be observed. The number and appearance of images depend on the angle, mirror arrangement and viewing conditions.
In a physics laboratory, this apparatus gives students a way to observe the relationship between mirror orientation and multiple image formation. It can be used to complement theoretical lessons about reflection, virtual images and geometrical optics.
Principle of Multiple Image Formation Between Two Mirrors
A plane mirror forms a virtual image by reflecting light. When two plane mirrors are placed at an angle, light may undergo repeated reflections between them. These successive reflections can produce multiple images of the same object.
Relationship Between Mirror Angle and Image Count
For two ideal plane mirrors inclined at an angle θ, the number of images depends on the ratio of 360 degrees to the angle and on the symmetry of the object and mirror arrangement.
m = 360° / θHere, θ is the angle between the mirrors. When 360°/θ is an integer, the observed image count can depend on whether the object lies on the angle bisector. For a non-integer ratio, the commonly used ideal estimate is the integer part of 360°/θ. Actual observations may vary with the experimental setup.
This relationship provides a useful starting point for understanding multiple reflections. Students should compare their observations with the theoretical prediction and account for the actual arrangement used in the experiment.

What is the Angle Between Mirrors experiment?
It is a physics experiment that investigates how two plane mirrors placed at an angle can produce multiple images through repeated reflection.
What is the principle of the Angle Between Mirrors apparatus?
The apparatus demonstrates the laws of reflection and multiple image formation. Light can reflect repeatedly between two inclined plane mirrors, producing several virtual images.
How does the angle between two mirrors affect image formation?
In general, decreasing the angle between two plane mirrors increases the number of images that can be observed. The exact count depends on the angle and object placement.
What is the formula for the number of images between two mirrors?
A commonly used relationship is based on 360° divided by the angle between the mirrors. For an integer ratio, object placement and symmetry determine the applicable image count; otherwise, the integer part is commonly used for the ideal estimate.
