What is near-infrared?

Near-infrared is like invisible light that you can feel but not see, kind of like a warm hug from the sun on your face.

Imagine you're playing with a remote control for your TV. When you press a button, it sends out signals to make the TV work. These signals are made of light, but they’re not the kind you see, they’re near-infrared light. It’s like a soft whisper from the remote that your TV can hear.

Think about sunlight. You can see the colors, like blue and red, but near-infrared is like an extra layer of warmth hiding just beyond the red part of the rainbow. Your skin feels this warmth when you’re outside on a sunny day, it’s like the sun is giving you a gentle warm-up.

Some cameras and phones use near-infrared to take pictures in the dark, kind of like having night vision without needing special goggles.

So, near-infrared is like that quiet friend who gives you extra warmth when you need it most. Near-infrared is like invisible light that you can feel but not see, kind of like a warm hug from the sun on your face.
