A photon that's 10.2 eV has a wavelength of $1.21\times10^{-7} m$, which is UV light. Less energetic light (e.g. blue-to-red) just doesn't have enough energy to kick up that electron. So the photons pass through because they can't be absorbed.
But solar panels only work well under certain conditions, and sometimes damage to the protective layer is unavoidable. Solar panels will work through clear plastic, but not all plastics are the same. The type of plastic you use plays a role in maintaining the effectiveness of the solar panel. Adding an additional layer will likely result in a
Popular answers (1) Although we routinely use UV lamps inside our biosafety cabinets and assume that UV light does not penetrate through matter, there are many reports that suggest this might not
Fluorescent lights are also prone to emitting UV light. During operation, an electrical discharge stimulates gas- neon or mercury vapor in argon. This reaction causes the emission of UV radiation. A protective dye or phosphor coating covering the bulb absorbs the harmful UV bands and allows visible light to pass through.
Transmission occurs when UV rays pass directly through the plastic, reflection happens when the UV rays bounce off the surface of the plastic, and absorption occurs when the UV rays are absorbed into the plastic. The Number of UV Rays that Penetrate Plastic Depends on its Thickness
UV can travel well through plastic, but not through silicate-based glass. Radio waves can travel through brick and glass, but not well through a metal box. Each of these differences has a slightly different answer, but each answer is based on molecular resonance or crystalline structure (or lack thereof) or electrical conductivity.
Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [2] or organic material as activators.
Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica , BK7 and sapphire ; however, the performance of an optical system can be optimized by using
It can be made with a variety of UV and other coatings, and many industries employ plexiglass because of its versatility. For example, manufacturers use plexiglass for light and instrument casings in cars, and to make appliances and eyewear lenses. Manufacturers use the sheet form of plexiglass for: windows; lights; signs; bathtubs; furniture and
