Imagine you're looking at a mirror, and it shows only the front of your face, not the back. That's because the mirror reflects light from the side that is facing it, like how a friend can only see what you’re showing them, not what’s on your back. Light travels in straight lines, so when it hits the mirror, it bounces back to our eyes, helping us see our reflection.
Examples
- A mirror reflects what’s facing it like a friend who can’t see behind you.
- You can't look at your back in a mirror unless you turn around.
