The sun is a strong source of ultraviolet radiation, but atmospheric absorption eliminates most of the shorter wavelengths. The eyes are quite susceptible to damage from ultraviolet radiation. Welders must wear protective eye shields because of the uv content of welding arcs can inflame the eyes. Snow-blindness is another example of uv inflamation; the snow reflects uv while most other substances absorb it strongly.
Ultra-violet light has a shorter wavelength and higher energy compared to visible light. Our eyes are only able to detect wavelengths between 400-700 nanometers, which is the range of visible light. Ultra-violet light falls outside of this range, making it invisible to the human eye.
Yes, some animals such as bees, birds, and reptiles have the ability to see ultra-violet light. This is because their eyes have specialized cells called cones that are sensitive to ultra-violet light. This allows them to navigate and locate food more efficiently.
We can use special instruments such as cameras or spectrophotometers to detect ultra-violet light. These instruments use technology that is able to capture or measure the intensity of ultra-violet light. Additionally, some objects may fluoresce or glow under ultra-violet light, making it easier to detect.
Prolonged exposure to ultra-violet light can be harmful to our eyes. The sun emits a significant amount of ultra-violet radiation, which can cause damage to the cells in our eyes and increase the risk of developing cataracts. This is why it is important to wear sunglasses or other protective eyewear when exposed to sunlight.
Yes, it is possible to manipulate ultra-violet light through various methods such as filtering, reflecting, or refracting it. Scientists and engineers use these techniques to create specialized equipment and devices that use ultra-violet light for different purposes, such as sterilization, printing, and curing materials.
