When water hits a screen.

    When water hits the screen. You can see that a specific pattern. A special kind of pattern color pattern can be seen in the drops.. I am able to see that the colors green, red and blue come forward very distinctly. Is there an easy explanation for this?

    I think I can guess what you are asking. :smile:

    That drop of water acts like a magnifying lens on your computer screen. It magnifies what lies underneath it. And what your screen is made up of are lots and lots of pixels, small rectangular dots of colour. It the colour being displayed is white, then all those dots will be lit up equally.

    In addition to what was said in post #2, keep in mind that your computer screen only has red blue and green pixels, so that's what you see.
