Light Absorption and colour Filters
When white light shines on a red object, all of the colors that form the white light are absorbed ExceptRed, which is reflected. This is why the object appears red. A FilterIs a transparent material that absorbs some colors and allows others to pass through.
Light is the only source of colour. colour pigments (paints, dyes, or inks) show colour by absorbing certain parts of the light spectrum and reflecting the parts that remain. colour filters work the same way, absorbing certain wavelengths of colour and transmitting the other wavelengths.
