The image in plane mirror is same size as the object
Explanation:
- Plane mirror is a mirror with a flat or planar reflective surface. The angle of reflection is always equal to the angle of incidence for all the light rays, which strike upon the plane mirror.
- Mirrors are polished surfaces coated with mercury . They follow laws of reflection . Mirrors are designed such that they reflect most of the light falling on them.
- Also size of image in a plane mirror is equal to the size of the object. Image is virtual and upright in nature.
- Therefore if a person's height is 1.7m , image height will also be the same which is 1.7m.
- Length of image will be 1.7m.
