Objective:
To find out what happens if you put highlighter ink into water and expose it to UV light and why, and observe which highlighter ink glows more in the dark.
Background information:
Ultra violet light and visible light are both a part of the electromagnetic spectrum. In this experiment, the Ultra violet flashlight transmits UV rays, which illuminates materials that have phosphor in them, transforming the UV light into visible light.
Phosphors are a synthetic fluorescent or phosphorescent substance, substances that emit light when excited by radiation.
Highlighter ink has phosphor, which is why it glows when it is under the UV rays flashlight; it’s a reaction of the exposure of phosphors to radiation.
This experiment uses a type of luminescence called fluorescence, which means that my glowing water will only glow when exposed to the UV rays flashlight.
Bright colors reflect more color , dark colors absorb more color. Thats why black is a color that absorbs all colors while white is a color that reflects all colors.
