I want to thank my mom for buying all the materials that I needed. I want to thank Mr. Gorcowski for answering the questions that I had.
Introduction
UV light produced by the sun is blocked from the Earth’s atmosphere, but some still gets onto the earth. UV beads have a pigment the changes color when exposed to ultraviolet light radiation. The dye in the UV bead is photo chromic that changes color when exposed to UV, which is chemical reaction.
Review Literature
UV, or ultraviolet, light is an invisible form of electromagnetic radiation that has a shorter wavelength than the light humans can see. It carries more energy than visible light and can sometimes break bonds between atoms and molecules, altering the chemistry of materials exposed to it.
Ultraviolet-sensitive beads are beads that change color in the presence of ultraviolet radiation. Ultraviolet rays are present in sunlight and light from various artificial sources, and can cause sunburn or skin cancer.
Johann Wilhelm Ritter was born in 16 December 1776 in Samitz (then Silesia, Germany, now Chojnow, Poland). In 1802–1803 he built the first dry cell battery and accumulator. In 1801 Ritter discovered ultraviolet radiation by chemical means.
The near ultraviolet, abbreviated NUV is the light closest to optical or visible light. The extreme ultraviolet, abbreviated EUV, is the ultraviolet light closest to X-rays, and is the most energetic of the three types. The far ultraviolet, abbreviated
