TV remote control trick. Not a question but try this out...?

Take a TV remote control and look at its front end and press a button. Can you see anything? No.

Now do the same but look at it through a camera phone. You can see it flickering!

Amazing huh.

    That's funny.. :D That's because in TV remote control they use near-infrared ray emission which cannot be detected by human eye because wavelength of them are 0.75-1.4 µm. It's longer than the visible light, but your phone can detect it - the flickering is the impulse in which rays are emitted .. so that's the whole trick.
