Under UV light, crows' feathers may appear iridescent or shiny due to the presence of special proteins that reflect UV light. This can give them a unique and striking appearance compared to how they look in normal light.
Yes, wasps are attracted to UV light. UV light can mimic the light spectrum of flowers, which are a food source for wasps. This attraction to UV light can lead wasps to light sources such as outdoor lights or bug zappers.
Mosquitoes are attracted to UV light because it mimics the light emitted by certain flowers, which they use as a visual cue to find nectar. The UV light also helps them navigate and locate potential hosts for blood meals.
Yes, UV light can produce ozone during the disinfection process. UV light can react with oxygen in the air to create ozone, which can help in disinfecting surfaces and air.

Glass is not suitable for use in UV spectroscopy because it absorbs UV light, leading to inaccurate measurements due to spectral interference. Quartz is preferred as it is transparent to UV light, allowing for accurate UV spectroscopic measurements without interference.
Sperm may appear whitish or yellow under UV light due to the presence of fluorescent molecules in semen.
Highlighters contain fluorescent molecules that absorb UV light and re-emit it as visible light, making them appear to glow under UV light. These molecules typically have conjugated double bonds that allow them to absorb light energy and then emit it at a longer wavelength, creating the glowing effect.
Skin may appear to glow under a black light because the ultraviolet (UV) light causes certain compounds in the skin, like proteins and oils, to fluoresce. This fluorescence makes the skin appear to emit a glow when exposed to the light.
Black light emits ultraviolet (UV) light, so it typically excites fluorescent materials that absorb UV light and re-emit visible light. Fluorescent colors that appear bright under black light include neon colors like pink, green, orange, and yellow. Other colors without fluorescent properties may appear muted or black under black light.
Detergent contains fluorescent molecules that absorb ultraviolet light and re-emit it as visible light, causing it to glow under a black light. This phenomenon is known as fluorescence and is often used in laundry detergents to make clothes appear brighter under UV light.
Laundry detergents often contain optical brighteners that fluoresce under ultraviolet light, such as a black light. These brighteners absorb UV light and re-emit it as visible blue light, making white clothes appear brighter and whiter. This is why laundry detergent may appear to glow under a black light.
Urine will typically appear fluorescent or bright yellow-green under a UV (ultraviolet) light due to the presence of riboflavin (vitamin B2) in urine. The intensity of the fluorescence can vary depending on factors such as hydration levels and vitamin intake.
under uv lights, different inks appear differently, e.g. it fluoresces. if the forged signature is diffrent from the rest of the document, chances are that the signature is forged
The fluorescence color of amethyst under UV light is typically a light pink or reddish-purple hue.
Metals are not oxidized by UV radiation.
Blood may show up as a dark brown color under a black light due to the presence of heme molecules in red blood cells, which can absorb and reflect light in the UV spectrum. This can create a fluorescence effect that makes blood appear darker or black when exposed to UV light.
Fluorescent or neon colors, such as bright greens, pinks, and yellows, tend to show up prominently under ultraviolet (UV) light. These colors appear to glow because certain dyes and pigments react to UV light by emitting visible light.
