The different types of uv light
WebLight Emitting Diodes (LED) are just the mechanism that emit the ultraviolet (UV) light/rays. The difference between what we refer to as an LED vs UV lamp consists of two things: what puts out the light (diodes or an old school long bulb) and the wavelength of the light that the thing (diode or old school long bulb) puts out.. They both will emit UV rays, and it's true … WebUV light has a shorter wavelength than visible light. Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of "purpler-than-purple" light or "beyond violet" light.

WebApr 3, 2024 · However, they’re very different. The UV-B light has a medium wavelength, ranging between 290 nm to 320 nm. So, it is more harmful than UV-A light. While the atmosphere absorbs most of the solar UV-B light, it can still affect our bodies. Luckily for us, it won’t penetrate more than just the superficial skin layer. WebUltraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds. The beneficial effects of UV radiation include the production of a vital nutrient, vitamin D; however, overexposure may present risks. Sunburn, premature aging, and skin cancer are all risks to overexposure.
