Ultraviolet light is a type of light we can’t see but that affects our skin every day.
Imagine you're playing outside on a sunny day and your skin gets warm, even when it's not too hot. That’s because the sun sends out different kinds of light, like visible light (what we see) and ultraviolet light (which we can’t see). It's like having invisible friends who also come with you to play.
How it works
Ultraviolet light has more energy than the light we normally see. When it hits our skin, it can make us feel warm or even cause a sunburn, just like how touching something hot feels different from touching something cool.
Why it matters
Some people use special lotions called sunscreen to protect their skin from ultraviolet light, kind of like wearing gloves when you're about to touch something really hot. This helps keep our skin healthy and happy, even on the sunniest days!
Examples
- A child gets a sunburn after playing outside without sunscreen.
- Fluorescent markers glow under black lights at a party.
- Doctors use UV light to treat certain skin conditions.
