difference b/w erect,virtual and laterally inverted

This is the nature of the image formed by the plane mirror.

Erect means upright or having a vertical position.

Virtual means image than can’t be captured on a screen.

 Lateral inversion is the effect produced by a plane mirror in reversing images from left to right. As we observe our image on a plane mirror, we can see that our left side is at the right side of the image and our right side is at the left side of the image.
