What are flashes?

Flashes are quick bursts of light that happen suddenly, just like when you turn on a flashlight really fast.

Imagine you're playing hide and seek in a dark room. All of a sudden, someone turns on a bright light, whoosh! That’s what a flash feels like. It's not the whole room lighting up at once; it’s more like a short, bright burst that makes everything visible for just a moment.

Flashes can be caused by many things. Sometimes they come from lightning, which is like nature’s version of a super-bright flashlight. Other times, flashes are made by machines, like the ones in cameras or phones when you take a picture in the dark. These machines use a special kind of light to make sure everything shows up clearly.

Think of it like this: if your room was really dark and you wanted to see something, you’d flick on a bright lamp for just a second, that’s a flash!
