Understanding the properties of images formed by plane mirrors is essential in optics.

Description

Properties of Images in Plane Mirrors

Images formed by plane mirrors are virtual, upright, and the same size as the object. The distance from the object to the mirror equals the distance from the mirror to the image.

  1. a

    Calculate the distance from the mirror to the image if the object is placed 2 meters away from the mirror.

    Aim for approximately 2 distinct marking points.
