In summary, the conversation discusses the concept of transparency and the role of glass in allowing certain wavelengths of light to pass through. It is explained that glass is transparent to visible light, but absorbs UV light due to the energy levels of the electrons in the material. However, it is also noted that glass is opaque to lower Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths Plastic degradation, as a result of UV light absorption, leads to discoloration, cracks, and loss of mechanical and physical properties [1,2]. Photooxidation resembles autooxidation due to long-term heat aging, except that the driving force is UV light and not heat . Therefore, during plastic manufacturing, measures should be taken to ensure Lots of pure plastics fail to absorb UV radiation, risking your project and its components. How to Avoid UV Degradation. You, avoid UV degradation in plastics by using blockers, stabilizers, or absorbers. Benzophenones and other organic compounds can also absorb UV light and emit it as heat. For example, plastic may not be efficient for UV-range experiments, but it is a cost-effective alternative for all the visible light studies. It is important to bear in mind that oxygen present in the atmosphere absorbs significantly below 200 nm and nitrogen absorbance assumes significance below 190 nm. How does the sun affect the color of plastic? The UV light is not good for skin (burns the skin) and therefore human skin exposed to sun produces pigments to absorb the light to protect the skin from burning. The produced pigments result in a colour change. Plastics: Plastics are one of the most drastically effected materials from sunlight. We can see visible light emitted by the sun. But the sun also emits light we can’t see, including UV light. Quinine is a substance found in tonic water that is sensitive to UV light. It can absorb UV light that we can’t see and then re-emit visible blue light that we can see. This process of converting ultraviolet into visible light is Scientists have known for a while that melanin absorbs UV light and converts it into heat, but the precise mechanism by which melanin does this has – until now – been unclear. .
