If Richard looks into a mirror and touches his left ear with his right hand Richards image seems to touch its right ear with its left hand?

This phenomenon is due to the lateral inversion that occurs in mirrors. When Richard looks into a mirror, his left side appears on the right side of the mirror image, and vice versa. This is because the mirror reflects light in a way that reverses the left-right orientation of objects. Therefore, when Richard touches his left ear with his right hand, his mirror image appears to touch its right ear with its left hand.
