plz help me. y do detection beads change colour when exposed to fluorescent lamp|?

I need help on knowing why ultraviolet detection beads change colour when exposed to fluorescent lamps. thanks. plz answer

Answer 1

These beads contain different pigments that change color when exposed to ultraviolet light from any source – including the sun. The beads are all white in visible light. In UV light, depending on the pigment added to each bead, you will see different colors. Each bead will change color about 50,000 times before the pigment will no longer respond to UV light.

Answer 2

OK..so you have these beads, and you know that they change color when exposed to ultraviolet light, right? If you hold them under a fluorescent light, they also change color? If that's the case, then you could conclude that the fluorescent light is emitting some ultraviolet light.

If this isn't what you're after, let me know, or try to rephrase your question.
