Flicker (light)

Flicker is when the light in a room or from a lamp turns on and off quickly. It's like a light switch that's turning on and off really fast. Sometimes it happens so fast that your eyes can't even see it, but your brain can still detect it.

If you've ever been in a room where the light flickers a lot, you might have felt like it was making you dizzy or giving you a headache. That's because your brain and body feel uncomfortable when the light keeps changing so quickly.

There can be different reasons why a light flickers. Sometimes it's because the light bulb is old or the wiring in the house is not working properly. Other times it can be because of something happening in the electricity that powers the light.

So if you ever see a light flickering, it's important to tell an adult so they can figure out what's going on and fix it so the light is stable and doesn't flicker anymore.
