In this post, we will explore the fascinating world of reflection and how images are formed by plane mirrors. Reflection occurs when light rays bounce off a surface, following a specific set of rules known as the law of reflection. According to this law, the angle of incidence and the angle of reflection are always equal. This can be mathematically represented as θi = θr, where θi is the angle of incidence and θr is the angle of reflection.

To understand image formation in plane mirrors, let's consider an example. Suppose we have an object placed in front of a plane mirror. Rays of light emanating from the object strike the mirror's surface. According to the law of reflection, these rays bounce off the mirror and travel in a different direction, forming an image.

The image formed by a plane mirror is virtual, upright, and located behind the mirror. It is at the same distance from the mirror as the object, known as the object distance. The image distance is equal to the object distance, but on the opposite side of the mirror. This forms a characteristic feature of plane mirrors, where the image appears to be located behind the mirror at a distance equal to the distance of the object from the mirror.
