Virtual and Erect image formed by plane mirror

Introduction: A plane mirror is a flat reflective surface that reflects light in such a way that the image of an object in front of it appears behind the mirror. The image formed by a plane mirror is virtual, erect, and of the same size as the object.

Explanation: When light falls on a plane mirror, it undergoes reflection. The angle of incidence is equal to the angle of reflection, and the image formed is virtual, meaning it cannot be projected on a screen. The image is also erect, which means it is not inverted. The image appears to be behind the mirror, and the distance of the image from the mirror is equal to the distance of the object from the mirror.

Real and Inverted Images: The real image is formed when the light rays coming from an object meet at a point after reflection. Real images can be projected on a screen. An inverted image is formed when the image is upside down compared to the object. This happens when the object is placed beyond the focus of a concave mirror or between the focus and the mirror.

Applications of Plane Mirrors: Plane mirrors are commonly used in everyday life, including in bathrooms, dressing rooms, and in car mirrors. They are also used in optical instruments such as periscopes, kaleidoscopes, and cameras.

Conclusion: In summary, the image formed by a plane mirror is virtual and erect. It is not inverted and cannot be projected on a screen. Plane mirrors are commonly used in everyday life and in optical instruments.
