See the Invisible - Phone Camera Infrared Experiment

Hey, welcome back to Kids Fun Science! Today, we're doing a cool science experiment that shows how your camera phone can see what your eyes can't. This simple remote setup reveals the invisible infrared light emitted by your TV remote, offering a fantastic lesson in basic physics for science for kids. Join us to see how this works and learn about the light spectrum around us!

Now push any button on your TV remote and look carefully to see if you can spot anything going on the front of the remote… you won’t. Now point the TV remote control unit directly into your cell camera's lens and watch the display while pressing that button again. I had to use the front camera on my iPhone, as the back camera didn’t work for some reason. This time, you'll see a little white or purple light on your TV remote. Stop pressing and the light stops. Your cell camera's 'EYE' can 'SEE' the TV remote control unit's infrared signal and the screen converts this invisible chatter to visible white light. Whats the Science behind this? The remote control units in your house uses a infrared light to transmit your ever-changing desires to a small detector on their corresponding unit. Human eyes can't see this infrared light. A remote's infrared signal is a bit like Morse code. Each TV remote in your house speaks a different 'language' that prevents the television doing strange things when you use the DVD's remote. Different manufacturers use different codes, which is why your old remote won't work on your brand new TV. Even different models from the same manufacturer will speak a different 'language' to avoid communicating with other devices. To successfully send its signal, your TV remote needs a direct line of sight between its light emitting diode and the detector on your device. But why can you see this invisible infrared light through your digital camera's eyes? Well, you can't really. Human eyeballs cannot see infrared light no matter how hard you might like to try. Your camera's light detectors, however, really are sensitive to infrared light. The camera's internal circuitry sends the infrared signals that its detectors 'see' to the liquid crystal display (LCD), which then emits them as visible light that your eyes can, and do, see.
