Watch on YouTubeVideoReflection and mirrors
When light hits a smooth shiny surface, it bounces back — this is reflection.
A plane mirror gives an image that is:
- Same size as the object
- As far BEHIND the mirror as the object is in FRONT
- Laterally inverted — left and right are swapped
- Virtual (can't catch it on a screen)
Example
"AMBULANCE" is painted reversed on the front of an ambulance so the driver in front, looking in their rear-view mirror, reads it correctly.
💡 Tip:Lateral inversion is ONLY left↔right, not up↔down.
