Today we worked on Light #11...Filtering white light. We used a green, blue and red filter...to filter different wavelengths of light from white light. We discovered that a red filter allowed red wavelengths through easily, and absorbed or blocked the other wavelengths. That is why we see everything as red, when we look through a red filter.
